Abstract
Description
技术领域
本发明涉及一种红色磷光主体化合物和使用该化合物的有机发光管器件,更具体而言,涉及一种具有优异的色纯度和高亮度及发光效率的可溶性磷光主体化合物以及使用该化合物的OLED器件。
背景技术
随着多媒体技术的发展及信息化要求的提高,对面板显示器性能的要求越来越高。其中,OLED具有自主发光、低电压直流驱动、全固化、视角宽、颜色丰富等一系列的优点,在新一代显示器和照明技术中的潜在应用而引起广泛注意,应用前景十分广阔。有机电致发光器件是自发的发光器件,OLED发光的机理是在外加电场作用下,电子和空穴分别从正负两极注入后在有机材料中迁移、复合并衰减而产生发光。OLED的典型结构包括阴极层、阳极层、电子注入层、电子传输层、空穴阻挡层、空穴传输层、空穴注入层和有机发光层中的一种或几种功能层。
尽管有机电致发光的研究进展非常迅速,但仍有很多亟待解决的问题,比如外量子效率(EQE)的提高,色纯度更高的新材料的设计与合成、高效电子传输/空穴阻挡新材料的设计与合成等。对于有机电致发光器件来说,器件的发光量子效率是各种因素的综合反映,也是衡量器件品质的一个重要指标。
发光可以分为荧光发光和磷光发光。在荧光发光中,单线态激发状态的有机分子跃迁至基态,由此发出光。另一方面,在磷光发光中,三线态激发状态的有机分子跃迁至基态,由此发出光。
目前来看,部分有机电致发光材料由于其性能优秀,已经在商业上有所应用,但作为有机电致发光器件中的主体材料,除了三线态能级要高于客体材料,防止激子跃迁释放的能量逆传递以外,更重要的是具有良好的空穴迁移性能。目前,主体材料中同时具有高三线态能级和良好空穴迁移率的材料仍然缺乏。因此,如何设计新的性能更好的主体材料,一直是本领域技术人员亟待解决的问题。
