Definitions

  • the present invention relates to the field of organic electronic devices, and in particular to an organic functional compound, a mixture, a composition, an organic functional film, a method for preparing the same, and an organic electronic device.
  • OLEDs Organic light-emitting diodes
  • OLEDs have been invented since the invention (Appl. Phys. Lett. 1987, 51: 913-15.; Nature, 1990, 347: 539-541) due to the synthetic diversity of organic materials and relatively low manufacturing costs. And has excellent optical and electrical properties, making it a great potential for applications in optoelectronic devices such as flat panel displays and lighting (Chem Rev, 2009, 109: 897-1091; Chem Mater, 2011, 23: 326) -340).
  • OLED devices mostly use a multilayer device structure, that is, in addition to the light-emitting layer, one or more layers of hole transport/injection layers or electron transport/injection layers. Therefore, in addition to the development of excellent luminescent materials, the development of excellent electron transport/injection materials and hole transport/injection materials is also the key to achieving high performance OLEDs (J Mater Chem, 2008, 18: 4495-4509.; Acc Chem Res, 2005). , 38: 632-643.; Adv Mater, 2007, 19: 810-814).
  • OLEDs Although small molecules are easy to obtain multilayer, complex and highly efficient OLEDs by vacuum evaporation, vacuum evaporation methods have the disadvantages of being expensive, time consuming, wasteful of materials, and difficult to achieve large area applications. In contrast, solution-processed OLEDs have broad application prospects and commercial value because they have the advantages of being able to prepare large-area, flexible devices by low-cost inkjet printing, printing and other solution processing methods. Since general organic photoelectric materials have similar solubility, that is, organic/polymer luminescent materials, hole injection/transport materials, electron injection/transport materials in toluene, chloroform, chlorobenzene, o-dichlorobenzene, o-xylene, tetrahydrofuran, etc.
  • the organic solvent has good solubility, so that when the solution is processed to prepare a multi-layer, complex OLED, there are problems such as interface miscibility and interface erosion.
  • interface miscibility and interface erosion For example, when a solution is processed into a polymer or a small molecule light-emitting layer, the solvent used dissolves the underlying hole transport layer, causing problems such as interfacial miscibility and interface corrosion (J Mater Chem, 2008, 18: 4495-4509.; Chem Soc Rev, 2010, 39: 2500-2521).
  • the cross-linking cured polymer HTM has been used to solve the above problems.
  • a conventional cross-linking group such as a perfluorocyclobutane group, a styryl group, a butylene group, a silicone group, an acrylate group, a benzocyclobutane group, or the like, a modified conjugated polymer, a polymer
  • the above crosslinking group initiates perfluorocyclobutane (Adv. Funct. Mater., 2002, 12, 745), styrene (Adv. Mater., 2007, 19, 300), epoxy under conditions of illumination, heat, and the like. Butanyl (Nature, 2003, 421, 829.), silicone based (Acc. Chem.
  • the crosslinkable polymers reported so far are based on conjugated polymers.
  • Most conjugated polymers have lower triplet energy levels, which quench adjacent luminescent layers, such as excitons with higher triplet energy (relatively shorter wavelengths) in the green luminescent layer, and do not To the role of the exciton blocking layer. These all limit the performance improvement of solution processing OLED devices.
  • the materials of the light-emitting layer including soluble small molecules and light-emitting polymers, are mostly non-crosslinkable and solidified. Because cross-linking curing has a great influence on the performance of the luminescent layer. Therefore, the electron transport layer and/or the electron injection layer must also be prepared by a vacuum evaporation method.

Description

有机功能化合物、混合物、组合物、有机功能薄膜及其制备方法和有机电子器件 技术领域
本发明涉及有机电子器件领域,特别是涉及一种有机功能化合物、混合物、组合物、有机功能薄膜及其制备方法和有机电子器件。
背景技术
有机发光二极管(OLEDs)自发明以来(Appl.Phys.Lett.1987,51:913-15.;Nature,1990,347:539-541),由于有机材料具有合成上多样性、制造成本相对较低,且具有优良的光学与电学性能,使得其在光电器件(例如平板显示器和照明)的应用方面具有很大的潜力(Chem Rev,2009,109:897-1091;Chem Mater,2011,23:326-340)。
OLED器件大多采用多层器件结构,即除了发光层外,还含有一层或多层空穴传输/注入层或电子传输/注入层。因此,除了开发优异的发光材料,开发优异的电子传输/注入材料和空穴传输/注入材料也是实现高性能OLED的关键(J Mater Chem,2008,18:4495-4509.;Acc Chem Res,2005,38:632-643.;Adv Mater,2007,19:810-814)。
虽然小分子很容易通过真空蒸镀方法获得多层、复杂的高效OLEDs器件,但是真空蒸镀方法具有价格昂贵、耗时、浪费材料、难以实现大面积应用等缺点。相比而言,由于溶液加工型OLEDs具有能够通过低廉的喷墨打印、印刷等溶液加工方法制备大面积、柔性器件等优点,使其具有广泛的应用前景和商业价值。由于一般有机光电材料具有相似的溶解性,即有机/聚合物发光材料、空穴注入/传输材料、电子注入/传输材料在甲苯、氯仿、氯苯、邻二氯苯、邻二甲苯、四氢呋喃等有机溶剂中具有良好的溶解性,使得在溶液加工制备多层、复杂的OLED时,会存在界面混溶、界面侵蚀等问题。例如溶液加工聚合物或小分子发光层时,所使用的溶剂会溶解下面的空穴传输层,造成界面混溶、界面侵蚀等问题(J Mater Chem,2008,18:4495-4509.;Chem Soc Rev,2010,39:2500-2521)。
一直以来人们都采用可交联固化的聚合物HTM来解决上述问题。常规的交联基团,如全氟环丁烷基、苯乙烯基、环氧丁烷基、硅酮基、丙烯酸酯基、苯并环丁烷基等修饰的共轭聚合物时,聚合物上的交联基团在光照、加热等条件下会引发全氟环丁烷基(Adv.Funct.Mater.,2002,12,745)、苯乙烯基(Adv.Mater.,2007,19,300)、环氧丁烷基(Nature,2003,421,829.)、硅酮基(Acc.Chem.Res.,2005,38,632)、丙烯酸酯基(Chem.Mater.,2003,15,1491)及苯并环丁烷基(Chem.Mater.,2007,19,4827.)等可交联基团发生交联反应,形成不溶不熔的互穿网络聚合物膜,具有优异的抗溶剂性能,可以避免界面混溶、界面侵蚀等问题(TW201406810A,US7592414B2)。
但迄今为止报道的可交联高聚物都是基于共轭聚合物。共轭聚合物大多具有较低的三线态能级,会淬灭相邻发光层,如绿光发光层中具有更高三线态能量(相对更短的波长)的激子,同时也不会起到激子阻挡层的作用。这些都制约了溶液加工OLED器件的性能的提高。
另外,到目前为止,发光层的材料,包括可溶性小分子和发光聚合物,大多是不可交联固化的。因为交联固化对发光层的性能影响极大。因此电子传输层和/或电子注入层还必须通过真空蒸镀的方法制备。
因此,急需开发一种能够通过溶液加工的方法制备功能层的有机化合物,且该有机化合物能够避免界面混溶、界面侵蚀等问题。
发明内容
基于此,有必要提供一种能够通过溶液加工的方法制备有机电子器件的功能层的有机功能化合物,且该有机功能化合物能够避免界面混溶、界面侵蚀等问题。
此外,还提供一种含有该有机功能化合物的混合物、组合物、有机功能薄膜及其制备方法和有机电子器件。

有机材料的能级结构中,三线态能级E T、HOMO、LUMO起着关键的作用。以下对这些能级的确定做一介绍。
HOMO和LUMO能级能够通过光电效应进行测量,例如,XPS(X射线光电子光谱法)、UPS(紫外光电子能谱)等,还能够通过循环伏安法(以下简称CV)。最近,量子化学方法,例如密度泛函理论(以下简称DFT),也成为行之有效的计算分子轨道能级的方法。
有机材料的三线态能级E T能够通过低温时间分辨发光光谱来测量,或者,还能够通过量子模拟计算(如通过Time-dependent DFT)得到,如通过商业软件Gaussian 09W(Gaussian Inc.),具体的模拟方法可以参考专利文件WO2011141110中的方法,或者也可以本实施方式后面介绍的方法获得。
应该注意,HOMO、LUMO和E T的绝对值取决于所用的测量方法或计算方法,甚至对于相同的方法,不同的评价方法也会导致结果的不同,例如在CV曲线上起始点和峰点会给出不同的HOMO/LUMO值。因此,合理有意义的比较应该用相同的测量方法和相同的评价方法。本实施方式中的HOMO、LUMO、E T的值是基于Time-dependent DFT的模拟获得的,需要说明的是,HOMO、LUMO、E T的获得也不限于采用该方法,它们也可以通过其它测量方法或计算方法获得,然而不同方法确定的能级值应进行相互标定。
在本文中,HOMO、LUMO不是一个绝对的值,它是一个相对与标准材料NPB(见如下化学式)的值。应作如下理解:按照本文的方法(见具体实施例),NPB的HOMO为-5.22eV,LUMO为-2.34eV。因此,较为准确的,本文对HOMO、LUMO要求,当涉及不同方法时,要作相应的校准。
