摘要
有机室温磷光(room temperature phosphorescence,RTP)材料凭借制备简单、类型丰富、毒性低等特点,以及在显示、传感、生物成像等方面广阔的应用前景而备受关注.一般的有机RTP材料,其磷光寿命<10 ms,而具有长寿命(τ>100 ms)有机RTP材料其磷光衰减过程裸眼可见,因而具有更广阔的应用前景.本文总结了近年来兼具高效率和长寿命有机RTP材料的分子设计策略,包括引入重原子、形成主-客体材料、构筑H聚集、形成氢键和设计成DonorAcceptor(D-A)结构.
Organic room-temperature phosphorescent(RTP)materials are simple to prepare,rich in types,low in toxicity.RTP materials have broad applications in display,sensing,and biological imaging.Most organic RTP materials show a phosphorescent lifetime of<10 ms,but those with longer phosphorescent lifetime of>100 ms have advanced and wider applications as their phosphorescence decay is visible to the naked eye.This paper reviews molecular design strategies of organic RTP materials with high quantum efficiency and long lifetime.Introduction of heavy atoms,formation of host-guest materials,construction of H-aggregation,formation of hydrogen bonds,design of donor acceptor(D-A)structures are emphasized.
