Aggregation-induced emission (AIE) materials with photocyclization (PC) reactions exhibit rich photophysical and photochemical activities. Understanding the mechanism behind is essential to the design of effective AIE materials. Herein, we employ a polarizable continuum model (PCM) and the hybrid quantum mechanics and molecular mechanics (QM/MM) approach, to study the luminescent properties of PC-typed AIEgens, SIP-2 and DPI, in both solution and crystalline states. The calculated results indicate that the fluorescence quantum yields ( |
