资源简介：
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 phase, only one diastereomer (S,R,R)-1b was produced. No such diastereoselection was observed in the α-crystalline
phase.
