Synthesis and Properties of a New Diarylethene Bearing n-Hexyl for Holographic Optical Recording
A new photochromic compound 1-(2-ethyl-3-benzothienyl)-2- (2-n-hexyl-5-formyl-3-thienyl) perfluorocyclopentene (1a) was synthesized, its photochromic properties were examined, the result indicated that the color of the compound 1a changed from colorless to a blue one upon irradiation with 297 nm UV light, a new absorption maxima were observed at 583 and 594 nm in hexane and PMMA film, respectively. The new photochromic compound also exhibited remarkable holographic optical recording character.
