Abstract

Abstract: A novel benzothiazole azobenzene based photochromic compound BTA was synthesized through diazocoupling reaction. Its chemical structure was confirmed, and the photoresponsive properties, mechanism, and application prospects were studied by using UV-vis spectra, PL spectra, FT-IR spectra, and theoretical calculations. The results indicated that based on the mechanism of cis-trans isomerization, BTA solution rapidly changed from yellow to colorless and emitted blue fluorescence under UV light irradiation and can be restored to its initial state by visible light irradiation under 60 ℃ heating, exhibiting reversible dual-mode photochromic phenomenon. The film prepared by doping BTA with polymethyl methacrylate (PMMA) successfully achieved erasable optical information storage. This study provides valuable insights and experimental evidence for the design of dual-mode photochromic materials and their applications in smart optoelectronic devices.
