Synthesis and Properties of a New Diarylethene1-[2-methyl-5-(10-phenanthrenyl)-3-thienyl]-2-[2-methyl-5-(4-formylphenyl)-3-thienyl]perfluorocyclopentene

Abstract:

A new photochromic diarylethene based on a phenanthrene, which is named 1-[2-methyl-5-(10-phenanthrenyl)-3-thienyl]-2-[2-methyl-5-(4-formylphenyl)-3-thienyl] perfluorocyclopentene, was designed and constructed successfully. At the same time, its photochromic properties, kinetics and fluorescence switch were investigated in detail. The results indicated that its photochromic behaviors could be modulated by UV/Vis light, changing from colorless to blue in dichloromethane solution. What is more, the kinetic experiments illustrated that the cyclization/cycloreversion process of this compound was determined to be the zeroth/first reaction. Furthermore, the optical switch experiment illustrated that the diarylethene 1o functioned as a remarkable fluorescent switch.
