Paper Abstract

A novel photochromic dithienylethene, [1-(2-methyl-5-formyl-3-thienyl)-2-(2-methyl-5-naphthyl-3-thienyl)]perfluoro- cyclopentene (1a), was synthesized and its photochemical properties, such as photochromism in solution as well as in poly-methylmethacrylate (PMMA) amorphous film, fluorescence were investigated in detail. Dithienylethene 1a has shown good photochromic behavior both in solution and in PMMA film. Upon irradiation with 254 nm UV light, its color changed from colorless to blue, in which absorption maxima were observed at 584 nm in hexane and 596 nm in PMMA film. 1a also showed relatively strong fluorescence in different solvents when excited at 292 nm. In addition, photon-mode holographic optical storage using dithienylethene 1b as recording medium was performed successfully.
