摘要

Abstract

The fluorescent probe techniques have been widely applied. When the fluorescence probes are selectively located in nanostructures

the fluorescence properties are highly influenced by the environment. Here

we systematically studied the location-influenced fluorescence of AIEgens in the microphase-separated structures. The AIEgen tetraphenylethene (TPE) was doped into polystyrene-

-polyisoprene (PS-

-PI). TPE was selectively located in the PS nanodomains. The TPE fluorenscence was affected by the structural relaxation of PS when investigated in a wide range of temperatures

including the glass transiton and secondary transiton. When TPE groups were selectively located in the PI nanodomains

the fluorenscence was affected by the glass transitons of PI and PS blocks. Amphiphilic TPE derivative was located at the interface of the assembly. The fluorescence emission was influenced by the main transition and secondary transiton of PS blocks

as well as the main transition of PI blocks. These results would give new understanding of the interrelation between fluorescence probes and the nanostructures.
