Abstract
Two new photochromic diarylethene compounds, {[1-(2-methyl-5-(4-(2-(1,3-dioxolane))phenyl)),2-(2-methyl-5-(p-methylphenyl))]thien-3-yl}perfluorocyclopentene (1a) and {[1-(2-methyl-5-(4-(2-(1,3-dioxolane))phenyl)),2-(2-methyl-5-(4-formyl- phenyl))]thien-3-yl}perfluorocyclopentene (2a), were synthesized. Their spectra properties, such as UV-Vis absorption spectra, fluorescence and kinetics properties in solution were also investigated. Diarylethene 1a shows relatively strong fluorescence at 353 nm when excited at 295 nm, and 2a shows no fluorescence under the same experimental condition. The cyclization/cycloreversion processes of the two diarylethenes were determined to be zeroth/first order reaction, respectively. In addition, photo-mode multi-step optical storage using 2a as recording medium was performed successfully.
