Disparity in piezofluorochromism for twisted mono-carbazole-based AIEgens resulting from interchanging electron-rich substituents: effect of coplanarity on twisted π-conjugates

Abstract

Newly established carbazole-based aggregation-induced emission-active fluorogens are recognized with piezo-fluorochromic features that vary with the effect of planarity. Suitable probe is demonstrated as a platform for rewritable optical recording.
