Abstract
A photoswitchable foldamer containing an azobenzene and phenyl-1,2,3-triazole motif was found to show photochemical/dark isomerization in a controllable and reversible manner in both the absence and presence of anions. The transformation in conformation of the foldamer leads to changes in binding affinities for anions to a certain extent that depends on the size and the geometrical shape of the anions.
摘要
一种含有偶氮苯和苯并[1,2,3]三唑基序的光致变色折叠体被发现可以在不存在和存在阴离子的情况下以可控和可逆的方式进行光化学反应/暗异构化。折叠体构象的转变导致对阴离子的结合亲和力发生变化，在一定程度上取决于阴离子的大小和几何形状。
