Photochromic materials have attracted widespread attention due to their potential applications in optical information storage, optoelectronic devices, and fluorescence probes. As a typical photochromic system, diarylethene derivatives are considered one of the most promising outstanding photostability significant bistable properties. Based on an aggregation-induced emission (AIE) mechanism, this study employed molecular structural engineering strategy design synthesize series containing ethyl benzoate substituents. A systematic investigation structure–activity relationship between behavior AIE characteristics revealed dual-state light response mechanism solid solution states. This demonstrates that target compounds exhibited responses under UV–visible irradiation, with enhanced state compared state, confirming remarkable enhancement effect aggregation. Structural characterization techniques such as nuclear magnetic resonance spectroscopy (NMR) high-resolution mass spectrometry (H RMS) were elucidate correlation conformation photophysical Furthermore, these demonstrated for multi-level anti-counterfeiting, high-density bioimaging applications, providing experimental foundations development novel multifunctional materials.
