摘要
双极性蓝光荧光材料因其双极传输特性和发光特性,为有机电致发光器件性能提升及结构简化提供了新途径。大多数双极性蓝光荧光材料在结构上符合电子给体-π桥-电子受体(D-π-A),根据电子受体单元,本文将其分为二苯磷/磺酰类、二米基硼类、五元杂环类、六元氮杂环类等,讨论了各类材料结构特点及在器件中的应用性能,对非D-π-A型材料也进行了总结。同时,介绍了热活化延迟荧光特性的双极性蓝光荧光材料的进展情况。最后,对双极性蓝光荧光材料中存在的问题进行了提炼,并展望了其发展前景。
Bipolar blue fluorescent materials capable of bipolar charge transport and possessing high photoluminescence quantum yields have paved the way for the development of high-performance and simple structure organic light-emitting devices. Bipolar blue fluorescent materials with the general architecture of＂donor-π bridge-acceptor＂mainly include diphenyl phosphoryl/sulfonyl based compounds,dimesitylboryl-based compounds,five-membered heterocyclic based compounds,six-membered N-heterocyclic based compounds,their molecular structure and device performances are reviewed in this article,materials without the ＂D-π-A ＂structure are also introduced. In addition,materials with thermally activated delayed fluorescence properties,which have received much attention,are summarized. Finally,the challenges and prospective tendency of the bipolar blue fluorescent materials are given based on the current research.
