AIE-induced fluorescent vesicles containing amphiphilic binding pockets and the FRET triggered by host-guest chemistry

A series of tetraphenylethylene (TPE)-bile acid conjugates was described. It was found that the synergetic combination of the distinct properties of TPE and bile acid units could directly afford uniform fluorescent vesicles with amphiphilic binding pockets in the membrane. This structural features of such vesicles provides a unique opportunity for facile construction of functional chemical systems through host-guest chemistry.
