摘要：
We designed and prepared novel MFC materials (TPE-B, TPE-T) with D-pi-A scaffolds containing thiazolo[5,4-d]thiazole and TPE units. The results proved that TPE-B and TPE-T exhibited obvious AIE properties and reversible MFC behavior. The performance in solid state of TPE-B and TPE-T presented that the mechanical force led to 25-28 nm red-shift, and could recover to the original state by solvent soaking. The powder XRD reveal that the morphological change from crystalline to amorphous state could be responsible for mechanochromism. Moreover, TPE-B and TPE-T could be constructed the rewritable information storage systems. This research work provides valuable reference for the design of MCF mate-rials. (c) 2022 Elsevier B.V.
