Synthesis and Properties of 1-[2-methyl-5-(2-methoxylphenyl)-3-thienyl]- 2-[2-methyl-6'-(diethylamino)-2-(4-cyclopent-methylene-amino-2'- hydroxyspiro (isoindoline-1, 9'-xanthen))]-3-thienyl] Perfluorocyclopentene

Abstract

A new unsymmetrical photochromic diarylethene 1-[2-methyl-5-(2-methoxylphenyl)-3- thienyl]-2-[2-methyl-6'-(diethylamino)-2-(4-cyclopent-methylene-amino-2'-hydroxyspiro (isoindoline-1, 9'-xanthen))]-3-thienyl] perfluorocyclopentene (1O) has been drafted and constructed triumphantly, and its photochromic properties, fatigue resistance, photochromic cyclization/cycloreversion kinetics and fluorescence were studied at great length. Moreover, the diarylethene showed fluorescence switches upon irradiation with UV/Vis. The present results are useful for the design of efficient and excellent characteristic diarylethene compounds.
