WO2014/167286(Kathirgamanathan,其公开内容通过引用结合在本文中)关注提供更多具有空穴传输性能的化合物或者在备选的方案中提供改进的具有空穴传输性能的化合物的问题,并且除其它外公开了空穴传输材料,该空穴传输材料具有连接到除烷基取代的芴外的共轭或芳族烃的一个、两个或三个噻蒽结构部分。所述化合物的一些实施方案据说显示了令人惊讶地有利的空穴迁移率和高玻璃化转变温度或熔点的组合,使得它们可以用在空穴注入层和/或用在电子封闭层。因为它们通常是小分子,它们中的许多可通过升华纯化,这对于OLED和其它器件应用所要求的纯度的化合物的生产来说是希望的。所报道的具体化合物包括:4-(噻蒽-1-基)三苯基胺(也称为二苯基-(4-噻蒽-1-基苯基)胺)(HTS-1);4,4',4”-三(噻蒽-1-基)三苯基胺(也称为三(4-噻蒽-1-基苯基)胺;HTS-2);9-(4-噻蒽-1-基苯基)-9H-咔唑(HTS-3);4,4'-二(噻蒽-2-基)三苯基胺(苯基-二(4-噻蒽-1-基苯基)胺;HTS-4);4-(10H-吩噻嗪-10-基)三苯基胺(N-(4-(10H-吩噻嗪-10-基)苯基)-N-苯基苯胺;HTS-5);和2,8-二(1-噻蒽基)二苯并噻吩[HTS-8]。与α-NPB相比较的HOMO和LUMO能级显示如下。
Kathirgamanathan中关于盒结构、阳极、空穴注入体和空穴传输层、空穴注入材料、电致发光材料、电子传输材料、电子注入材料和阴极的一般教导通过引用全部结合到本文中。
