Mechanochromic luminophores have attracted considerable attention for their potential applications in various fields. This review summarizes the tetraphenylethylene-functionalized compounds and complexes with aggregation-induced emission and discusses their mechanoluminochromic mechanisms.
Mechanochromic luminophores that display luminescent changes upon exposure to external mechanical force have received considerable attention due to their promising applications in numerous fields includ-ing mechano-sensors and data recording. High brightness aggregative-state emission has great signifi-cance for achieving effective applications of mechanochromic luminogenic molecules, and luminophores with aggregation-induced emission effect are capable of exhibiting strong aggregative-state luminescence. In this review, we summarize the aggregation-induced emission-active tetrapheny-lethylene-functionalized compounds and complexes with mechanochromic luminescence characteristics, as well as discuss their mechanoluminochromic mechanisms. This review will provide a valuable refer-ence for the potential opportunities and future challenges in this fascinating scientific field.(c) 2022 Elsevier Ltd. All rights reserved.
