Abstract
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.
