Lanthanide Complexes with Aggregation-induced Emission

摘要

聚集诱导发光(AIE)镧系配合物结合了镧系离子独特的光物理性质与AIE特性, 在多个领域具有应用价值. 然而, 迄今尚未有文献对该领域的研究进展进行系统梳理. 本文基于镧系中心数目总结了AIE镧系配合物的研究进展, 并阐述了其作用机制及在刺激响应和生物成像等领域的应用. 最后, 简要探讨了AIE镧系配合物当前面临的挑战及未来研究方向.

Abstract

Lanthanide complexes with aggregation-induced emission（AIE） integrate the unique photo-physical properties of lanthanide ions and the AIE features， making them applicable in diverse areas. However， the progress in this area has been rarely reviewed. Herein， we summarize the advance of AIE lanthanide complexes based on the number of lanthanide centers they contain， along with the mechanism and applications in the fields of stimulus- responsive and biological imaging. Meanwhile， the current challenges and the future research directions in this area are also briefly discussed.
