Description

一种含有芴的芳胺化合物及其有机电致发光器件
技术领域
本发明涉及有机光电材料技术领域,具体涉及一种含有芴的芳胺化合物及其有机电致发光器件。
背景技术
随着人们对显示和照明的要求越来越高,有机发光二极管(Organic Light-Emitting Diode,以下简称为OLED)凭借其厚度小、重量轻、视角宽、响应时间短、应用温度范围宽、能耗低、发光效率高、色纯度好、可弯曲性好等优点,备受显示企业及照明企业的青睐。
邓青云等人在1987年首次将有机物层叠加在一起形成发光器件,这奠定了OLED的发展基础。OLED研究者们不断优化器件的结构,并努力开发出光电特性好的OLED材料,发展至今,较早期的OLED,目前OLED的器件性能已经在某些方面超越了传统的液晶器件,得到了较广泛的应用。
OLED的器件呈三明治结构,包括外侧的金属阴极和ITO阳极,在阴极和阳极之间夹有有机物层,而有机物层又细分为不同的功能层,例如:空穴注入层、空穴传输层、电子传输层、电子注入层、发光层等。在外电场的作用下,空穴和电子分别从阳极和阴极向有机物层注入,然后通过空穴传输层和电子传输层进入发光层,在发光层中二者复合产生激子,并释放能量,激子在电场的作用下迁移,将能量传递给发光层中的发光物质,激发发光物质分子中的电子,使其从基态跃迁到激发态,电子从激发态回到基态时,能量以光的形式释放出来,从而产生发光现象。
目前应用到OLED器件中的空穴传输材料主要以有机胺类化合物为主,这是因为有机胺类化合物具有高的空穴迁移率,并且具有较低的最高占据分子轨道(HOMO)值和较低的三线态能级(T1)值。但是,从另一方面,这会使在发光层中产生的激子容易向空穴传输层转移,造成发光层内的电荷不均衡,导致在空穴传输层界面发光,降低OLED器件的发光效率。
发明内容
为了解决上述的技术问题,本发明提供一种含有芴的芳胺化合物,具有如下通式(I)所示结构:

其中,所述的Ar1选自碳原子数是6~30的芳基或碳原子数是3~30的杂芳基,
所述的Ar2选自氢原子、氘原子、碳原子数是6~30的芳基、碳原子数是3~30的杂芳基中的一种,并且Ar2在每次出现时可以相同,也可以不同,
所述的R1~R8独立地选自氢原子、氘原子、卤原子、氰基、碳原子数是1~12的烷基、碳原子数是1~4的烷氧基、碳原子数是6~30的芳基、碳原子数是3~30的杂芳基中的一种,并且R1~R8在每次出现时可以相同,也可以不同,并且所述的R1~R8中至少有两个相邻基团连接成环,
所述的L1、L2独立地选自单键、碳原子数是6~30的亚芳基、碳原子数是3~30的亚杂芳基中的一种,并且L2在每次出现时可以相同,也可以不同,
上述芳基、杂芳基、亚芳基、亚杂芳基分别由选自氘原子、卤原子、氰基、碳原子数是1~4的烷基、碳原子数是1~4的烷氧基、碳原子数是6~30的芳基、碳原子数是3~30的杂芳基组成的组中的一种以上的取代基取代或未取代,当被多个取代基取代时,它们能够相同或不同。
本发明还提供一种有机电致发光器件,包括阳极、阴极、有机物层,所述的有机物层中含有本发明所述的含有芴的芳胺化合物中的一种以上。
本发明的有益效果:本发明提供的含有芴的芳胺化合物,具有很好的空穴传输性能。由于该化合物将9位的碳被芳基或杂芳基取代的芴通过9位的取代基连接在芳胺的N上,一方面使化合物具有合适的HOMO值和T1值,能够有效降低激子向空穴传输层迁移,使发光层中的电荷均衡,避免在空穴传输层界面发光,从而提高器件的发光效率;另一方面,通过将连接位点选在9位的取代基上,使芳胺的N与芴环上的苯环未直接连接,打断了分子的共轭,使分子间堆积不会过于紧密,从而减小在外电场下分子间的相互影响,能够延缓材料的老化,进而延长器件的使用寿命。同时,本发明提供的化合物至少有一个芴环上的苯基稠合有苯基,增加了化合物的刚性,使化合物的热稳定性提高了,并且部分化合物至少含有一个被氘取代的取代基,由于氘与碳的连接键相较于氕与碳的连接键更不易断裂,进一步提高了分子的稳定性,使材料不易老化,从而进一步延长器件的使用寿命。由此可见,本发明提供的含有芴的芳胺化合物具有很好的光电性能及热稳定性,是一类性能优良的OLED材料。

将测试软件、计算机、美国Keithley公司生产的K2400数字源表和美国PhotoResearch公司的PR788光谱扫描亮度计组成一个联合IVL测试系统来测试有机电致发光器件的发光效率、电流密度、寿命。测试的环境为大气环境,温度为室温。测量结果如表1所示。

根据以上表1所示结果可以看出,对比化合物2比对比化合物1作为空穴传输层时的发光效率和使用寿命均有所提高,这是因为对比化合物2的芳胺的N连接在苯基芴的9位苯基上,一方面调整了化合物HOMO和T1值,避免界面发光,另一方面打断了分子的共轭,使分子堆积没有过于紧密,减小分子间相互影响,延长了使用寿命。将本发明的含有芴的芳胺化合物作为空穴传输层应用到OLED器件中,相较于使用NPB或对比化合物的器件具有更高的发光效率和更长的使用寿命,这主要是因为本发明的含有芴的芳胺化合物除了具有很好的空穴传输性能以外,相较于NPB及对比化合物具有更加合适的HOMO值和T1值,有效避免了空穴传输层的界面发光,从而提高了器件的发光效率;并且由于其具有打断共轭的分子结构,使分子间的相互影响减小,同时至少有一个芴环上的苯基稠合有苯基,增加了化合物的刚性,使化合物的热稳定性提高了,进一步提高了器件的使用寿命。
更进一步看出,含有五氘代苯基的本发明的化合物(12,19,22,44,58,70,80,90,100,130,152)比不含五氘代苯基的本发明的化合物(2,27,28,31,48,62,64,73,99,111,137,139,160)作为空穴传输层和第二空穴传输层时,可以获得更高的发光效率,以及更长的使用寿命,从而说明了氘代给化合物带来了不易老化以及更好的光电性能。
应当指出的是,本发明所公开的实施例仅为示例,用于解释说明本发明,并不用于限定本发明。本发明的保护范围应当根据发明要求保护的范围来解释,与其等同范围内的所有技术应解释为包括在本发明的保护范围内。
