Abstract

Reversibly-photoswitchable gold nanoparticles containing azobenzene and exhibiting a light response "virtually identical" to that of the free chromophore were achieved by self-assembling a host-guest inclusion complex between alpha-cyclodextrin and an azobenzene-terminated alkanethiol in an aqueous medium.

摘要

通过在水介质中自组装α-环糊精与偶氮苯封端的链烷硫醇之间的主客体包合物，制备出了含有偶氮苯且具有与游离发色团“几乎相同”光响应的可逆光开关金纳米粒子。
