A general and highly regioselective synthetic protocol for structurally diverse N-heteroaryl-fused phenanthridines has been developed. Varieties of fluorescence molecules comprising imidazole-fused, benzoimidazole-fused, indole-fused and pyrrole-fused phenanthridines were obtained by this modular approach, some of which exhibit excellent blue-emitting performance, high quantum yields, long fluorescence lifetimes, interesting electrochemical properties, and thermal stabilities.
已开发出一种通用且高度区域选择性的合成协议,用于合成结构多样的N-杂芳基融合荧光芳胺。采用这种模块化方法获得了多种荧光分子,包括咪唑融合、苯并咪唑融合、吲哚融合和吡咯融合的荧光芳胺,其中一些表现出优异的蓝光发射性能、高量子产率、长荧光寿命、有趣的电化学性质和热稳定性。
