Abstract
本发明涉及螺双芴衍生物及其在有机电致发光领域中的应用。本发明化合物可用于电子器件特别是有机电致发光器件、有机场效应晶体管、有机太阳能电池中,尤其适用于制备有机电致发光器件的发光主体材料、激子阻挡材料或电子传输材料。另外,本发明还涉及包含所述化合物的电子器件。
Description
技术领域
本发明属于有机光电材料技术领域,涉及间位取代螺双芴化合物和本发明化合物在电子器件特别是在有机电致发光器件、有机场效应晶体管、有机太阳能电池中的用途,尤其是在有机电致发光器件中用作发光主体材料、激子阻挡材料或电子传输材料,另外还涉及包含所述化合物的电子器件。
背景技术
满足各种信息显示需求的发光材料在信息时代的今天发展尤其迅速。发光材料主要分为无机和有机
两类,与无机材料相比,有机材料具有相对更高的发光效率和更宽的发光颜色选择范围以及具有大面积成膜的优势,引起研究者极大的兴趣。1987年柯达公司C.W.Tang等人首次报道以真空蒸镀的方法制备出Alq3为发光材料的双层发光器件,有力地推动了有机电致发光材料的发展。经过30多年的发展,有机电致发光在平板显示、照明方面的应用已经进入产业化初级阶段。从发光材料来分类,有机发光二极管(Organic Light-EmittingDiode,OLED)可以分为荧光、磷光以及热激发延迟荧光发光二极管。
有机电致发光器件一般包括由阳极、金属阴极和它们之间夹着的有机层组成。有机层主要有空穴注入层、空穴传输层、电子阻挡层、发光层、空穴阻挡层、电子传输层、电子注入层。另外,发光层大多采用主客体结构,即将发光材料以一定浓度掺杂在主体材料中,以避免浓度淬灭和三线态-三线态湮灭,提高发光效率。因此一般要求主体材料具有较高的三线态能级,并且同时具有较高的稳定性。
现有技术中主体材料多采用咔唑基团,可使得材料具有高额空穴传输能力,但咔唑基团C-N键容易分解,影响器件的耐久性。为了改善器件的稳定性,有报道设计具有螺环连接键的材料可具有加强的形态稳定性。螺双芴分子具有非平面的空间结构,两个芴单体以sp3杂化的C原子为中心桥联在一起,将其引入到具有电致发光特性的分子中,对于提高分子的热稳定性和光谱稳定性等方面具有很大的应用价值。目前,对于螺双芴衍生物的研究主要集中在其2位和4位(如CN102077384A和CN104541576A)。然而,2位和4位的衍生物一般具有较大的共轭度,分子的三重态能级较低,大大限制了其在蓝色有机电致发光器件中的应用。
发明内容
发明要解决的问题
为了解决以上现有技术的缺点和不足之处,有效提高三线态能级,改善有机电致发光器件的寿命、效率和工作电压等性能,本发明的目的是提供一种间位取代螺双芴化合物以及制备方法。
本发明的另一目的在于提供上述螺双芴类化合物的一种应用,特别是在有机电致发光器件中的应用。
本发明的再一目的在于提供一种包含所述化合物的电子器件。
