Abstract
The ability of an E-configured azobenzene guest to undergo photoisomerisation is controlled by the presence of a complementary host. Addition of base/acid allowed for a weakening/strengthening of the interactions in the divalent pseudo[2]rotaxane complex and hence could switch on/off photochromic activity.
摘要
具有E构型的偶氮苯客体发生光异构化的能力受互补主体存在的控制。添加碱/酸会削弱/增强二价准[2]轮烷配合物中的相互作用，因此可以开启/关闭光致变色活性。
