An aza-15-crown-5-ether functionalized bisthienylethene (BTE-15C5) was synthesized, which can reversibly capture and release calcium ions by UV/Vis irradiation. After doping this photochromic bisthienylethene with a two-component lecithin-Ca(2+) organogel, the original deep-blue gel changed to light-blue fluid due to the cooperative binding with Ca(2+) by the open-form bisthienylethene dopant. Upon UV irradiation, the closed isomer was formed which released the Ca(2+) and the organogel was retrieved. Hence, a novel organic simple doped-type three-component photo-induced gel-to-sol transition system was constructed.
合成了一种氮杂-15-冠-5-醚功能化的双噻吩乙烯（BTE-15C5），它可以通过紫外/可见光照射可逆地捕获和释放钙离子。将这种光致变色双噻吩乙烯与两亲性磷脂酰胆碱-Ca（2+）有机凝胶混合后，由于开环形式的双噻吩乙烯掺杂剂与 Ca（2+）的协同结合，原来的深蓝色凝胶转变为浅蓝色流体。紫外光照射后，形成了闭环异构体，释放出 Ca（2+），同时凝胶得到回收。因此，构建了一种新型的有机简单掺杂型三组分光致凝胶-溶胶转变体系。
