合成了一种在活性碳原子上具有手性聚乙二醇侧链的光致变色二乙烯衍生物。在紫外和可见光照射下，二乙烯在乙酸乙酯和水中均发生光致变色反应。开环和闭环异构体表现出非激子耦合型CD谱，化合物发生了非对映选择性环化反应。
A photochromic diarylethene derivative having chiral polyethylene glycol side chains at the reactive carbon atoms was synthesized. The diarylethene showed a photochromic reaction upon irradiation with UV and visible light in both ethyl acetate and water. The open- and the closed-ring isomers showed a non-exciton-coupled-type of CD spectrum, and the compound underwent a diastereoselective cyclization reaction.
