Paper Abstract

{[1-(2-methyl-5-(4-N,N-dimethylphenyl)),2-(2-methyl-5-(2-(1,3-dioxoane)))]-thien-3-yl}perfluorocyclopentene (1a) and {[1-(2-methyl-5-formyl),2-(2-methyl-5-(2,2'-dicyanovinyl))]-thien-3-yl}perfluorocyclopentene(2a) were synthesized and rewritable photo-mode optical recording by the use of them were performed. The results showed that both of the two diarylethenes are very sensitive responsing to the corresponding wavelength recording laser, and the readout signals with high S/N ratio which was up to 30 to approximately 50% were obtained. The destruction of the readout and the photochromic properties of these diarylethenes in hexane solution and PMMA films were also discussed.
