Aggregation-Induced emissive molecule with large stokes shift based on naphthalimide and triphenylamine

  • 摘要: 聚集诱导发光(AIE)现象是近年来光电功能材料的研究热点之一. 已开发的聚集诱导发光材料其发射光谱大都位于短波长的蓝绿光区域. 利用发色团光谱重叠构建高效的能量转移过程,实现了大Stokes位移的聚集诱导发光分子的构建. 使用实验室开发的4-苯基萘酰亚胺(NIP)蓝光聚集诱导发光分子作为能量给体,使用红光的氰基乙烯基三苯胺(TPACN)为能量受体,构建出的分子(NIPTPACN)可以在360 nm紫外光激发下,实现608 nm的红光聚集诱导发光. NIPTPACN的Stokes 位移达到248 nm,聚集态荧光发光强度是单纯使用氰基乙烯基三苯胺的82.6倍. 该研究成功实现了基于能量转移的大Stokes位移聚集诱导发光分子构建,为长波发光和大Stokes位移聚集诱导发光分子的设计提供了新的策略.
