A Dual-Responsive Fluorescent Compound Exhibiting Turn-On Mechanoresponsive and Solvatochromism for Rewritable Optical Data Storage.

ABSTRACT: A novel mechanoresponsive and solvatochromic luminescent compound (MO-HBI) was designed by combining an ESIPT-active donor with a benzophenone acceptor, exhibiting reversible luminescence switching and aggregation-induced emission enhancement. The solvatochromic behavior of MO-HBI was systematically studied in solvents of varying polarity, revealing a distinct bathochromic shift in both absorption and fluorescence emission, with pronounced sensitivity attributed to the presence of a carbonyl group. Upon mechanical stimulation, MO-HBI undergoes a crystalline-to-amorphous phase transition, leading to a significant fluorescence increase and color change from faint yellow to yellow-green. Structural analysis and DFT computation confirm that mechanoresp
