A new unsymmetrical photochromic diarylethene 1-(2-ethyl-3-benzothienyl)-2-[2-octyl-5-formyl-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 blue upon irradiation with 297 nm UV light, in which absorption maxima were observed at 581 nm in hexane and at 582 nm in PMMA film, The results demonstrated that it can be potentially used as polarization holographic optical recording medium.
