摘要
采用经典的乌尔曼(Ullmann)反应合成了基于螺芴氧杂蒽和苯并恶唑苯胺的新型主体材料SFX-2-BOA、SFX-2'-BOA和SFX-3'-BOA。光谱测试表明该系列化合物的荧光发射能与部分常用的客体发光材料的吸收光谱重叠,从而实现Forster能量转移。循环伏安测试结果表明苯并恶唑苯胺的引入可以有效降低分子的LUMO能级和提升HOMO能级,可同时改进空穴和电子的注入与传输能力。
Three novel host materials such as SFX-2-BOA, SFX-2′-BOA and SFX-3′-BOA based on spirofluorene and （benzo[d]oxazol-2-yl）aniline were designed and synthesized by the typical Ullmann reaction. Fluorescent spectra of these compounds could overlap with some commonly-used light-emitting vips and realize Forster energy transfer between them. The HOMO level could be improved and the LUMO level could be reduced due to the introduction of the （benzo[d]oxazol-2-yl）aniline group seen from the results of the cyclic voltammetric （CV） measurement, which is beneficial to the injection and transporting of the holes and electrons.
