A new unsymmetrical photochromic diarylethene 1-(2,4-dimethyl-3-isoxazol)-2-[2-methyl-5-(2-chlorophenyl) -3-thienyl] perfluorocyclopentene (1a) has been synthesized. Its photochromic properties in solution and PMMA film were investigated. Diarylethene 1a changed the color from colorless to red upon irradiation with 297 nm UV light, in which absorption maxima were observed at 515 nm in hexane and at 526 nm in PMMA film, The results demonstrated that it can be potentially used as polarization holographic optical recording medium.

In the present study, we designed a novel unsymmetrical isomeric diarylethene derivative bearing both thiophene and anthracene moieties. Its photochromic properties and fluorescence were investigated in detail. In hexane solution, the open-ring isomer of the diarylethene 1 exhibited relatively strong fluorescence. The photochromic reaction kinetics indicated that the cyclization process of 1o belongs to the zeroth order reaction and the cycloreversion process belongs to the first order reaction. This new photochromic system also exhibited remarkable optical storage character.

A new unsymmetrical photochromic diarylethene compound, 1-(2,4-dimethyl-5-thiazolyl)-2-[5-(2-chlorobenzene)-2-methyl-3-thienyl]perfluorocyclopentene(1a), was synthesized and its photochromism and photo-induced anisotropy was investigated. Diarylethene 1a changed the color from colorless to Orange-red upon irradiation with 297 nm UV light, in which absorption maxima were observed at 479 nm in hexane and at 485 nm in PMMA amorphous film, respectively. It also showed good photochromism and functioned as an effective fluorescent photoswitch in solution. In hexane, the open-ring isomer of the diarylethene 1a exhibited relatively strong fluorescence at 428 nm when excited at 315 nm. This new photochromic system also exhibited remarkable optical storage character.

A new type photochromic diarylethene, 1-(2-ethylbenzo[b]thiophen-3-yl)-2- (2-methylphenyl)perfluorocyclopentene (1o), was synthesized, and its photochromic and fluorescent properties were investigated. This compound exhibited reversible photochromism and notable fluorescence photoswitches both in solution and in PMMA films. In addition, the fluorescence spectra of diarylethene 1o evidently depended on the concentration in hexane. Using diarylethene 1c/PMMA film as recording medium, optical recording was carried out successfully.
