Description

用於有機電致發光裝置之材料Materials for Organic Electroluminescent Devices

本發明關於一種包含式(H1)化合物和式(H2)化合物之組成物。本發明此外關於一種調配物，其包含一種包含式(H1)和式(H2)化合物之組成物及一種溶劑。最後，本發明關於一種包含該種組成物之電子裝置。The present invention relates to a composition comprising a compound of formula (H1) and a compound of formula (H2). The invention furthermore relates to a formulation comprising a composition comprising compounds of formula (H1) and formula (H2) and a solvent. Finally, the invention relates to an electronic device comprising such a composition.

用於電子裝置的功能性化合物之開發為目前深入研究的主題。特別地，目的為開發可用其達成改良電子裝置在一或多個相關特徵的性質(諸如，例如，裝置的功率效率和壽命以及發射光的色坐標)之化合物。 根據本發明，術語電子裝置尤其意指有機積體電路(OIC)、有機場效電晶體(OFET)、有機薄膜電晶體(OTFT)、有機發光電晶體(OLET)、有機太陽能電池(OSC)、有機光學檢測器、有機感光器(photoreceptor)、有機場淬滅裝置(OFQD)、有機發光電化學電池(OLEC)、有機雷射二極體(O-雷射)和有機電致發光裝置(OLED)。 特別感興趣的是提供使用於最後提及之稱為OLED的電子裝置之化合物。OLED的一般結構和功能原理為熟習該項技術者已知且描述於例如US 4539507中。 仍然需要關於OLED之性能數據的進一步改良，特別是鑑於廣泛商業用途，例如，用於顯示裝置或作為光源。就此而論，特別重要的是OLED的壽命、效率和操作電壓以及所達成的色值。特別地，在藍色發光OLED的情況下，關於裝置的效率、壽命和操作電壓之改良是有可能的。 達成該等改良的重要起點為發光體化合物的選擇及主體化合物的選擇。事實上，發光體化合物通常係與第二化合物組合用於發光層，該第二化合物係用作為基質化合物或主體化合物。發光體化合物在本文中意指在電子裝置操作期間發射光的化合物。主體化合物在此情況下意指以大於該發光體化合物的比例存在於混合物中之化合物。術語基質化合物和術語主體化合物可同義地使用。主體化合物較佳不發射光。即使多種不同的主體化合物存在於發光層的混合物中，彼等個別比例通常大於發光體化合物的比例，或若多種發光體化合物存在於發光層的混合物，則大於個別發光體化合物的比例。例如US 4769292中已描述關於螢光發射層中之該等實施態樣。 若多種化合物的混合物存在於發光層中，則發光體化合物通常是以較小量(即，以小於發光層的混合物中的其他化合物之比例)存在的組份。在此情況下，發光體化合物亦稱為摻雜劑。 從先前技術中已知的用於螢光發光體之主體化合物為多種化合物。發光層可包括一種主體化合物或更多種。包含萘并雙苯并呋喃基團之主體化合物已揭示於先前技術中(例如於WO 2020/089138中)。包含二苯并呋喃和蒽基團之主體化合物已揭示於先前技術中(例如於KR 10-2017-0096860和CN 109867646中)。 然而，仍然需要用於螢光發光體的其他主體材料或主體材料的組合，其可使用於OLED中並且導致在壽命、顏色發射和效率方面具有非常好的性質之OLED。更特別地，需要組合非常高的效率、非常好的壽命和非常好的熱穩定性之用於螢光發光體的主體材料或主體材料的組合。 此外，已知OLED可包含不同的層，其可在真空室中藉由氣相沈積施加或藉由從溶液處理。以氣相沈積為基礎之方法導致良好的結果，但該等方法複雜且昂貴。因此，也需要可從溶液容易且可靠地處理的包含OLED材料之組成物。更特別地，需要包含OLED材料之組成物，其當從調配物(更特別是從溶液如油墨)處理時在製造OLED期間可沉積成均勻之薄膜。在此情況下，該等材料在包含彼的溶液中應具有良好的溶解度，且包含OLED材料之沉積薄膜在導致移除溶劑的乾燥步驟後應儘可能的平滑。重要的是，沉積層形成平滑且均勻的薄膜，因為層厚度不均勻性造成不均勻的發光強度分佈，且膜厚度較薄的區域顯示增加的發光強度，而較厚的區域具有減少的發光強度，其導致OLED的品質下降。同時，包含從溶液處理的薄膜之OLED應呈現良好的性能，例如在壽命、操作電壓和效率方面。 此外仍然需要導致容易純化和容易處理之穩定的OLED材料之方法。需要藉由以可接受的純度和高產率提供OLED材料而在經濟和品質上令人感興趣之方法。 The development of functional compounds for use in electronic devices is currently the subject of intensive research. In particular, the aim is to develop compounds which can be achieved to improve the properties of electronic devices in one or more relevant features, such as, for example, the power efficiency and lifetime of the device and the color coordinates of the emitted light. According to the present invention, the term electronic device means especially organic integrated circuit (OIC), organic field effect transistor (OFET), organic thin film transistor (OTFT), organic light emitting transistor (OLET), organic solar cell (OSC), Organic optical detectors, organic photoreceptors (photoreceptors), organic field quenching devices (OFQDs), organic light-emitting electrochemical cells (OLECs), organic laser diodes (O-lasers) and organic electroluminescent devices (OLEDs) ). Of particular interest is the provision of compounds for use in the last-mentioned electronic devices known as OLEDs. The general structure and functional principles of OLEDs are known to those skilled in the art and are described, for example, in US 4,539,507. Further refinement of the performance data on OLEDs is still needed, especially in view of widespread commercial use, eg for display devices or as light sources. Of particular importance in this connection are the lifetime, efficiency and operating voltage of the OLEDs as well as the color values achieved. Especially in the case of blue-emitting OLEDs, improvements are possible with regard to the efficiency, lifetime and operating voltage of the device. An important starting point for achieving these improvements is the selection of the emitter compound and the selection of the host compound. In fact, the emitter compound is usually used in the light-emitting layer in combination with a second compound which acts as matrix compound or host compound. An emitter compound here means a compound that emits light during operation of the electronic device. A host compound in this case means a compound which is present in the mixture in a larger proportion than the emitter compound. The term matrix compound and the term host compound may be used synonymously. The host compound preferably does not emit light. Even if a plurality of different host compounds are present in the mixture of the emitting layer, their individual proportions are generally greater than the proportions of the emitter compounds, or, if a plurality of emitter compounds are present in the mixture of the emitting layer, than the proportions of the individual emitter compounds. Such implementations in fluorescent emissive layers have been described, for example, in US 4769292. If a mixture of compounds is present in the emitting layer, the emitter compound is usually a component present in a minor amount, ie in a smaller proportion than the other compounds in the mixture of the emitting layer. In this case, the emitter compounds are also referred to as dopants. Host compounds for fluorescent emitters are known from the prior art in a wide variety of compounds. The light emitting layer may include one kind of host compound or more kinds. Host compounds comprising a naphthobisbenzofuran group have been disclosed in the prior art (eg in WO 2020/089138). Host compounds comprising dibenzofuran and anthracene groups have been disclosed in the prior art (eg in KR 10-2017-0096860 and CN 109867646). However, there is still a need for other host materials or combinations of host materials for fluorescent emitters which can be used in OLEDs and lead to OLEDs with very good properties in terms of lifetime, color emission and efficiency. More particularly, there is a need for host materials or combinations of host materials for fluorescent emitters that combine very high efficiency, very good lifetime and very good thermal stability. Furthermore, it is known that OLEDs can comprise different layers, which can be applied by vapor deposition in a vacuum chamber or by processing from solution. Methods based on vapor deposition lead to good results, but are complex and expensive. Accordingly, there is also a need for compositions comprising OLED materials that can be easily and reliably processed from solution. More particularly, there is a need for compositions comprising OLED materials that can be deposited as uniform thin films during the manufacture of OLEDs when processed from formulations, more particularly from solutions such as inks. In this case, the materials should have good solubility in the solutions containing them, and the deposited film containing the OLED material should be as smooth as possible after the drying step leading to the removal of the solvent. It is important that the deposited layer forms a smooth and uniform film because layer thickness inhomogeneity causes a non-uniform luminous intensity distribution, and regions with thinner film thicknesses show increased luminous intensity, while thicker regions have decreased luminous intensity , which leads to a decrease in the quality of the OLED. At the same time, OLEDs comprising thin films processed from solution should exhibit good properties, eg in terms of lifetime, operating voltage and efficiency. Furthermore there remains a need for methods leading to stable OLED materials that are easy to purify and easy to handle. There is a need for an economically and qualitatively interesting method by providing OLED materials with acceptable purity and high yield.

本發明因此係基於提供適合用於電子裝置(諸如OLED)，更特別是作為螢光發光體之基質組份的包含OLED材料之組成物的技術目標。本發明亦是基於提供特別適合於溶液處理的包含OLED材料之組成物的技術目標。本發明亦基於提供方法的技術目標。 在對使用於電子裝置之新穎組成物之研究中，目前已發現，如下所定義之包含式(H1)化合物和式(H2)化合物之組成物非常適合使用於電子裝置。特別地，彼等達成上述技術目標之一或多者，較佳為全部。 本申請案因此關於一種組成物，其包含式(H1)化合物和式(H2)化合物，

The cathode of an organic electroluminescent device preferably comprises a metal with a low work function, a metal alloy or a multilayer structure comprising various metals, such as, for example, alkaline earth metals, alkali metals, main group metals or lanthanides (e.g. Ca, Ba, Mg , Al, In, Mg, Yb, Sm, etc.). Also suitable are alloys comprising alkali metals or alkaline earth metals and silver, for example alloys comprising magnesium and silver. In the case of multilayer structures, besides these metals, other metals with higher work functions can also be used, such as, for example, Ag or Al, in which case a combination of metals, such as, for example, Ca/Ag is usually used , Mg/Ag or Ag/Ag. It may also be advantageous to introduce a thin interlayer of a material with a high dielectric constant between the metal cathode and the organic semiconductor. Suitable for this purpose are, for example, alkali metal fluorides or alkaline earth metal fluorides, but corresponding oxides or carbonates (such as LiF, Li 2 O, BaF 2 , MgO, NaF, CsF, Cs 2 CO 3 , etc. ) is also suitable. Additionally, lithium quinolinate (LiQ) can be used for this purpose. The layer thickness of this layer is preferably between 0.5 and 5 nm. The anode preferably comprises a material with a high work function. The anode preferably has a work function greater than 4.5 eV versus vacuum. Suitable for this purpose are on the one hand metals with a high redox potential, such as, for example, Ag, Pt or Au. On the other hand, metal/metal oxide electrodes such as Al/Ni/ NiOx , Al/ PtOx may also be preferred. For some applications, at least one of the electrodes must be transparent or partially transparent in order to facilitate illumination of organic materials (organic solar cells) or coupling-out of light (OLEDs, O-lasers). Preferred anode materials here are conductive mixed metal oxides. Particularly preferred is indium tin oxide (ITO) or indium zinc oxide (IZO). In addition, conductive doped organic materials are preferred, especially conductive doped polymers. The device is structured appropriately (depending on the application), equipped with joints and finally sealed, since the lifetime of the device according to the invention is shortened in the presence of water and/or air. In a preferred embodiment, the organic electroluminescent device according to the invention is characterized in that one or more layers are coated by means of a sublimation method, wherein the materials are applied in a vacuum sublimation unit at temperatures below 10-5 mbar, more Preferably applied by vapor deposition at an initial pressure below 10-6 mbar. However, the initial pressure can also be even lower here, for example below 10-7 mbar. Also preferred is an organic electroluminescent device characterized in that one or more layers are coated by the OVPD (Organic Vapor Phase Deposition) method or supplemented by a carrier-gas sublimation method, wherein the materials are between 10 -5 mm applied at a pressure between bar and 1 bar. A particular example of this method is the OVJP (Organic Vapor Jet Printing) method, in which the materials are applied directly through nozzles and thus structured (e.g. MS Arnold et al. , Appl. Phys. Lett. 2008 , 92 , 053301 ). Further preferred is an organic electroluminescent device characterized in that one or more layers are formed such as, for example, by spin coating or by any desired printing method, such as, for example, screen printing, quick-dry printing, nozzle printing or lithography Printing, but particularly preferably LITI (Light Induced Thermography, Thermal Transfer Printing) or inkjet printing) from solution. Soluble compounds of formula (I) are required for this purpose. High solubility can be achieved through appropriate substitution of these compounds. Also possible are hybrid methods in which, for example, one or more layers are applied from solution and one or more other layers are applied by vapor deposition. Thus, for example, it is possible to apply the emitting layer from solution and the electron-transporting layer by vapor deposition. These methods are generally known to the person skilled in the art and can be applied by the person skilled in the art without an inventive step to organic electroluminescent devices comprising the compounds according to the invention. According to the invention, electronic devices comprising one or more compounds according to the invention can be used in displays, as light sources in lighting applications and as light sources in medical and/or cosmetic applications such as phototherapy. The invention will now be explained in more detail with the following examples, without wishing to limit the invention thereby.

b) 發光薄膜均勻性之評估 對於顯示器的製造，非常重要的是得到非常良好的像素均勻性而同時具有良好的裝置性能。層厚度的不均勻性造成不均勻的發光強度分佈，薄膜厚度較薄的區域顯示發光強度增加，而較厚的區域顯示發光強度減少。該不均勻性隨著像素而改變，從而阻止像素之間的可再現外觀。綜合而言，此將導致對該類顯示器的品質有負面看法。因此，本發明解決EML薄膜均勻性和裝置性能的課題。從而評估的第一步為檢測薄膜均勻性。為此，使用圖4a所示的堆疊。在EML沉積後停止處理。薄膜係如a)部分中所述製備。EML的組成物係顯示於表2-A和表2-B中。 為了評估印刷薄膜的均勻性，印刷薄膜的形貎係以輪廓儀(profilometer)沿著10µm輪廓特性化，並計算Rp-v(峰谷)值以及粗糙度的均方根差。使用來自KLA-Tencor Corporation之配備2 μm記錄針的輪廓儀Alpha-step D120測量薄膜輪廓。Rp-v值對應於在所測量的輪廓內之測得的最大峰(Rp)和最小峰(Rv)之高度差。為了便於查看，減去薄膜輪廓的基線，使得最小峰對應於0 nm高度且所有圖的軸刻度均相同。 下列二式係用於決定薄膜均勻性：峰谷差Rp-v，其表示層內之最大高度差(式1)，及均方根的粗糙度RMS，其使用高度差的均方根值對平均線z i(式2)。

對於具有輪廓PE2、PE3、PE4、PE5、PE6、PE7、PE8和PE9的發光層，與上述PE1相同的討論是有效的。 可比較使用具有輪廓 PE1至PE9的EML之裝置的性能與其他裝置(參見表5a 至5f)。對於根據本發明之所有發光層輪廓(PE2至PE7)，相較於單獨使用主體化合物2(PR4、PR6、PR8、PR10、PR12、PR14、PR16和PR18)，觀察到顯著較低的Rp-v和RMS值，而該等值與從單一主體化合物1(PR3、PR5、PR7、PR9、PR11、PR13、PR15、PR17)獲得之值相似。本發明超越單獨使用主體化合物1的優勢係說明於裝置結果部分。 c) 裝置結果 如圖4b中所示的裝置係根據a)部份製備。主體材料係顯示於表3中及發光體係顯示於表4中。藍色EML油墨係如表5a-f中所示混合，其亦顯示個別實例之在1000 cd/m 2下的相對外部量子效率(相對EQE)和相對裝置壽命(在1000 cd/m 2下的相對LT90)。

Yield: 0.96 g (2.1 mmol; 23%) Device example a) Preparation of thin films and devices Glass substrates covered with pre-structured ITO (50 nm) and blank material were cleaned in deionized water using ultrasound. Hereinafter, the substrates were dried using an air gun and then annealed on a hot plate at 225° C. for 2 hours. All following method steps were performed under yellow light. The following layer sequence is shown in Figures 4a and 4b. A hole injection layer (HIL) was inkjet printed on the substrate with a thickness of 20 nm and dried under vacuum. For this purpose, the HIL ink has a solids concentration of 6 g/l. The HIL was then annealed at 220°C for 30 minutes. Inkjet printing and annealing of HIL were carried out in air. As HIL material, a hole-transporting crosslinkable polymer and a p-doped salt were dissolved in 3-phenoxytoluene. These materials are described eg in (ie) WO2016/107668, WO2013/081052 and EP2325190. On top of the HIL, a hole transport layer was inkjet printed under ambient conditions, dried in vacuum and annealed at 220° C. for 30 minutes in an argon atmosphere. The hole transport layer is a polymer (HTM1) with the structure shown in Table 1, which is synthesized according to WO2013156130 or polymer HTM2 (Table 1), which is synthesized according to WO2018/114882. The polymer is dissolved in 3-phenoxytoluene such that the solution generally has a solids content of about 5 g/l if inkjet printing is to be used here to achieve a typical layer thickness of 20 nm for devices. The light-emitting layer contained a host material (one host compound or two host compounds) and a dopant as described in Table 2 below. The mixture used for the light-emitting layer was dissolved in 3-phenoxytoluene. The solutions have a solids content of 10 mg/ml if inkjet printing is to be used to achieve a typical layer thickness of 30 nm for devices. The blue light-emitting layer (B-EML) was also inkjet printed, followed by vacuum drying and annealing at 150° C. for 10 minutes. Inkjet printing was performed under ambient atmosphere, while annealing was performed under argon atmosphere. The device prepared according to Fig. 4a was used to evaluate the EML film uniformity. In order to prepare the device according to Figure 4b for electro-optic characterization, the sample was transferred to a vacuum deposition chamber where two electron transport layers (ETL1, ETL2), electron injection layer (EIL) and cathode ( Al) deposition. ETL1 is hereby composed of ETM1 (5nm film thickness) and ETL2 is composed of a 1:1 volume % mixture of ETM1 and ETM2 (40nm film thickness). The electron injection layer consisted of ETM2 (2nm) and the cathode was aluminum (100nm). The structures are shown in Table 1. After evaporation, the device was packaged in a glove box under an argon atmosphere.
Figure 02_image279
b) Evaluation of Luminescent Film Uniformity For the manufacture of displays, it is very important to obtain very good pixel uniformity while having good device performance. Inhomogeneity in layer thickness results in a non-uniform luminous intensity distribution, with regions of thinner film thickness showing increased luminous intensity and thicker regions showing decreased luminous intensity. This non-uniformity varies from pixel to pixel, preventing a reproducible appearance between pixels. Taken together, this will lead to a negative perception of the quality of this type of display. Therefore, the present invention addresses the issues of EML thin film uniformity and device performance. Thus the first step in the evaluation is to check the film uniformity. For this, the stack shown in Figure 4a is used. Treatment was stopped after EML deposition. Films were prepared as described in part a). The compositional systems of EML are shown in Table 2-A and Table 2-B. In order to evaluate the uniformity of the printed film, the shape of the printed film was characterized by a profiler (profilometer) along the 10µm profile, and the Rp-v (peak-to-valley) value and the root mean square difference of the roughness were calculated. Film profiles were measured using a profiler Alpha-step D120 from KLA-Tencor Corporation equipped with a 2 μm stylus. The Rp-v value corresponds to the measured height difference between the largest peak (Rp) and the smallest peak (Rv) within the measured profile. For ease of viewing, the baseline of the film profile was subtracted such that the smallest peak corresponds to 0 nm height and the axis scales are the same for all plots. The following two equations are used to determine film uniformity: the peak-to-valley difference Rp-v, which represents the maximum height difference within a layer (Equation 1), and the root mean square roughness RMS, which uses the root mean square value of the height difference to mean line z i (Equation 2).
Figure 02_image281
Figure 02_image283
Example PE1 comprising the host mixture according to the invention showed significantly reduced Rp-v and RMS compared to PR1 in which only host component 2 was used, and corresponded to smoother films ( FIGS. 1 and 3 ). Furthermore, Example PE1 also showed similar Rp-v and RMS values compared to PR2, resulting in better OLED performance as shown below (see Table 5b, Reference 3 and Example 2). Other thin film uniformities of the additional light-emitting layer (EML) are shown in Table 2-B below and the properties of OLEDs comprising corresponding EMLs are shown in Tables 5a to 5f.
Figure 02_image285
For luminescent layers with profiles PE2, PE3, PE4, PE5, PE6, PE7, PE8 and PE9, the same discussion as above for PE1 is valid. The performance of devices using EMLs with profiles PE1 to PE9 can be compared with other devices (see Tables 5a to 5f). For all emissive layer profiles (PE2 to PE7) according to the invention, significantly lower Rp-v was observed compared to host compound 2 alone (PR4, PR6, PR8, PR10, PR12, PR14, PR16 and PR18) and RMS values, which were similar to those obtained from single host compound 1 (PR3, PR5, PR7, PR9, PR11, PR13, PR15, PR17). The advantages of the present invention over the use of host compound 1 alone are illustrated in the Device Results section. c) Device Results The device shown in Figure 4b was prepared according to part a). The host materials are shown in Table 3 and the luminescent systems are shown in Table 4.

After encapsulation in the glove box, the OLEDs were characterized by standard methods. For this purpose, the electroluminescence spectrum, the current/voltage/luminous density characteristic curve (IUL characteristic curve) assuming the Lambert luminescence characteristic, and the (operating) lifetime are determined. The IUL characteristic curve is a characteristic diagram used to determine advantages such as external quantum efficiency (expressed in %) at a certain luminous intensity. The device was driven at a constant voltage at each step of the applied voltage ramp. The device lifetime was measured at a given current corresponding to the initial luminous intensity. Luminous intensity is then measured over time by the calibrated photodiode.

The illustrated embodiments of the mixed-body system all show improved device performance compared to single-body type H1 , while similar performance to body type H2 can be achieved. This is independent of the illuminant used and the illuminant concentration used. As mentioned above, the profiles of references 3, 4 and example 2 have been determined from Table 5b (see Figures 1 to 3). Compared to Reference 3, Examples 2 and 3 according to the invention show improved device performance in terms of efficiency and lifetime. Compared to Reference 4 which showed a very inhomogeneous film, the film comprising the hybrid host according to the invention was very homogeneous and at the same time showed similar device performance. The same argument is valid for the devices according to the invention shown in Tables 5a to 5f. By means of the present invention it is possible to achieve good OLED device performance while ensuring uniform film quality.
