solid-state greenish-blue emitting, mono-cyclometalated iridium complexes, [Ir(ppy)(PPh3)2(H)(Cl)], 2a and [Ir(F2ppy)(PPh3)2(H)(Cl)], 2b [ppyH = 2-phenylpyridine; F2ppyH = 2-(2′,4′-difluoro)phenylpyridine], have been synthesized by a convenient route. The ‘aggregation induced enhanced phosphorescence (AIEP)’ activity exhibited by these complexes has been rationalized.
发出强固态绿蓝光的单环
金属化
铱络合物[Ir(ppy)(PPh 3)2(H)(Cl)],2a和[Ir(F 2 ppy)(PPh 3)2(H) (Cl)],2b [ppyH =
2-苯基吡啶; F 2 ppyH = 2-(2',4'-二
氟)苯基
吡啶]是通过方便的途径合成的。这些配合物表现出的“聚集诱导的增强的
磷光(AIEP)”活性已得到合理化。
