Description
技术领域
本发明涉及有机电致发光材料技术领域,具体涉及一种含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物及其制备方法与应用。
背景技术
有机发光二极管(OLED)因具有高效、低电压驱动,易于大面积制备等优点得到人们广泛的关注。OLED的研究始于20世纪50年代,直到1987年美国柯达公司的邓青云博士采用三明治器件结构研制出了OLED器件在10V直流电压驱动下发光亮度可达到1000cd m-2,使OLED获得了划时代的发展。
OLED器件由阴极、阳极和中间的有机层构成,有机层一般包括电子传输层、发光层和空穴传输层,首先电子和空穴分别从阴阳两极注入,并分别在功能层中进行迁移,然后电子和空穴在合适的位置形成激子,激子在一定范围内进行迁移,最后激子发光。
为了早日实现有机/高分子电致发光器件的商业化,除了应满足能够实现全色显示、单色纯度高、热化学稳定性好和使用寿命长等要求外,还希望器件具有高的发光效率。目前影响OLED器件效率的主要因素之一是材料本身的电子和空穴传输注入的不平衡。因此,为了获得高效的OLED器件,获得具有合理调节电子空穴传输与注入平衡的材料显得尤为重要。
发明内容
本发明的目的在于提供一种启亮电压低、发光效率高的新型化合物,应用于制备有机电致发光器件的发光层。由于嘧啶、吡嗪、三嗪基团的还原电位比相似结构不含杂原子的芳香性基团更低,更利于接受电子,分别将缺电子的嘧啶、吡嗪、三嗪基团引入到蒽并茚并芴两侧,一方面有利于提高该化合物的电子接受能力和迁移率,另一方面有利于提供该化合物的成膜性,从而得到具有较高额电子传输性能、成膜性好、所应用的器件在室温下具有较好的稳定性的化合物。
本发明的目的还在于提供所述的一种含嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物的制备方法。
本发明的目的还在于提供所述的一种含嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物在制备有机发光二极管的发光层中的应用。
本发明的目的通过如下技术方案实现。
一种含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物,具有如下化学结构式:
式中,R1-R5分别独立选自氢、C1-C20的脂肪族烷基或C6-C20的芳香族基团;R6-R11选自氢、C6-C20芳基、碳原子数1-20的直链或支链烷基,或者碳原子数1-20的烷氧基;
Ar选自C4-C30的芳环、C4-C30的含氮杂环、C4-C30的稠合杂环芳烃、C4-C30的芳胺基或C4-C30的芳氧基;

A1~A4为N原子或C原子,组合情况包括:A1、A3同时为N原子,而A2、A4同时为C原子;或者,A1、A4同时为N原子,而A2、A3同时为C原子;或者,A2、A4同时为N原子,而A1、A3同时为C原子;或者,A3、A4同时为N原子,而A1、A2同时为C原子;或者,A1、A3、A4同时为N原子,而A2为C原子。
进一步地,含有A1-A4的六元环基团选自如下结构式:
进一步地,所述芳香族基团选自吡啶基、苯基或蒽基。
进一步地,所述稠合杂环芳烃中的杂原子选自N原子。
进一步地,所述含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物的化学结构式选自如下结构式:
式中,R6-R11选自氢、C6-C20芳基、碳原子数1-20的直链或支链烷基,或者碳原子数1-20的烷氧基。
制备所述的一种含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物的方法,包括如下步骤:
在氩气氛围下,先将含R6~R11的蒽并茚并芴单元制成中间体含R6~R11的蒽并茚并芴硼酸酯,然后再通过Suzuki偶联反应,将含有A1-A4的六元环基团及其余基团连接在蒽并茚并芴单元的两侧,得到所述含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物。
进一步地,所述Suzuki偶联反应的反应温度为110~160℃,反应时间为12~24小时。
所述的一种含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物在制备有机发光二极管的发光层中的应用,将所述的含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物用有机溶剂溶解,通过旋涂、喷墨打印或印刷成膜,制备得到有机发光二极管的发光层。
进一步地,所述有机溶剂包括氯苯。
与现有技术相比,本发明具有以下优点和有益效果:
(1)本发明的含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物,由于具有较大的共轭长度,所以有较高的荧光量子产率,有利于提高材料的器件效率;
(2)本发明的含有嘧啶或吡嗪或三嗪基团的蒽并茚并芴衍生物,具有较好的溶解性,基于化合物的发光层在制备电致发光器件时不用退火处理,使得制备工艺更简单。
