摘要

An optically active photochromic diarylethene,(S)-1-(2-methyl-5-phenyl-3-thienyl)-2-[2- methyl-5-(4-(3-methyl-1-penten-1-yl) phenyl)-3-thienyl] perfluorocyclopentene ((S)-1a), was synthesized.(S)-1a formed two crystalline phases, α-and β-phases. The diarylethene underwent a photochromic reaction in solution and even in the single-crystalline phase. In solution, no diastereoselection was observed. On the other hand, in the β-crystalline ...
