Abstract

本发明提供一种化合物,具有通式(1)所示结构,其中各基团如说明书中所定义。还提供包含所述化合物的有机电致发光器件。

Description

有机电致发光材料及其应用
技术领域
本发明涉及一种有机化合物,其可以用于有机电致发光器件中,特别地可用于发光层主体材料或空穴阻挡层材料;本发明还涉及该化合物在有机电致发光器件中的应用,以及包含该化合物的有机电致发光器件。
背景技术
近年来,基于有机材料的光电子器件已经变得越来越受欢迎。有机材料固有的柔性令其十分适合用于在柔性基板上制造,可根据需求设计、生产出美观而炫酷的光电子产品,获得相对于无机材料无以比拟的优势。此类有机光电子器件的示例包括有机发光二极管(OLED),有机场效应管,有机光伏打电池,有机传感器等。其中OLED发展尤其迅速,已经在信息显示领域取得商业上的成功。OLED可以提供高饱和度的红、绿、蓝三颜色,用其制成的全色显示装置无需额外的背光源,具有色彩炫丽,轻薄柔软等优点。
OLED器件核心为含有多种有机功能材料的薄膜结构。常见的功能化有机材料有:空穴注入材料、空穴传输材料、空穴阻挡材料、电子注入材料、电子传输材料,电子阻挡材料以及发光主体材料和发光客体(染料)等。通电时,电子和空穴被分别注入、传输到发光区域并在此复合,从而产生激子并发光。
人们已经开发出多种有机材料,结合各种奇特的器件结构,可以提升载流子迁移率、调控载流子平衡、突破电致发光效率、延缓器件衰减。出于量子力学的原因,常见的荧光发光体主要利用电子和空穴结合时产生的单线态激子发光,现在仍然广泛地应用于各种OLED产品中。有些金属络合物如铱络合物,可以同时利用三线态激子和单线态激子进行发光,被称为磷光发光体,其能量转换效率可以比传统的荧光发光体提升高达四倍。热激发延迟荧光(TADF)技术通过促进三线态激子朝单线态激子的转变,在不采用金属配合物的情况下,仍然可以有效地利用三线态激子而实现较高的发光效率。
随着OLED产品逐步进入市场,人们对这类产品的性能有越来越高的要求。当前使用的OLED材料和器件结构无法完全解决OLED产品效率、寿命、成本等各方面的问题。本发明的研究人员通过认真思考和不断实验,发现了一种巧妙的分子设计方案,并在下文中详细地进行说明。令人惊讶地,本发明所揭示的化合物非常适合应用于OLED并提升器件的性能。
