Abstract
A spiropyran-amide-dipicolylamine linkage behaves as a colorimetric receptor for selective Co(2+) sensing in aqueous media under UV irradiation. This is promoted by strong coordination of Co(2+) with amide oxygens of the receptors and efficient photoisomerization of the spiropyran moieties.
摘要
螺吡喃酰胺-二吡啶基胺键在紫外光照射下在水相介质中表现出对 Co(2+)的选择性比色响应，这是由于受体中亚胺氧原子与 Co(2+)的强配位作用和螺吡喃部分的有效光致异构化作用。
