Type: article
Abstract: An unsymmetrical diarylethene derivative was synthesized and its photochromic properties and fluorescence switch were investigated in detail. The results showed that this compound exhibited reversible photochromism, undergoing reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in solution and in PMMA film, and its absorption maxima were observed at 524 nm in hexane and at 532 nm in PMMA amorphous film, respectively, upon irradiation with 297 nm UV light. The PMMA film of the diarylethene 1a exhibited relatively strong fluorescence at 415 nm when excited at 318 nm. The fluorscence intensity is highest at the concentration of 1.0×10-4 mol/L when excited at 300 nm.
