Two novel photochromic dithienylethenes, [1-(2-methyl-5-p- methylphenyl-thien-3-yl)-2-(2-methyl-5(4-(1,3-dioxolane) phenyl)- thien-3-yl)]perfluorocyclopentene (DTE-1) and [1-(2-methyl-5-(3- thienyl)-thien-3-yl)-2-(2-methyl-5(4-(1,3- dioxolane)phenyl)-thien-3-yl)]perfluorocyclopentene (DTE-2), were synthesized and their photochemical properties, such as photochromism and fluorescence were investigated. DTE-1 and DTE-2 have shown good photochromic behavior. Upon irradiation with 254 nm UV light, their color changed from colorless to blue, in which absorption maxima were observed at 590 nm and 592 nm in CH2Cl2. DTE-1 and DTE-2 also showed relatively strong fluorescence in different solvents when excited at 295 nm. While, their fluorescence spectra showed remarkable concentration dependence. In addition, near-field recording using DTE-1 as recording medium was performed successfully.
