Study on Composite Photochromic Properties of New Diarylethenes Bearing Naphthyl Rings
A novel photochromic diarylethene, 1-[(2-methyl-5-(4-fluorophenyl)-3-thienyl)]-2-(2-methyl-1-naphthyl) perfluorocyclopentene (1o), was synthesized. Its optoelectronic properties, such as photochromism in solution as well as in poly-methylmethacrylate (PMMA) amorphous films, fluorescences 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 511 nm in hexane and at 522 nm in PMMA amorphous film, respectively, upon irradiation with 297 nm UV light.
