Abstract
Reported here is the synthesis of a new macrocycle bearing anionic carboxylate groups with water-soluble aggregation-induced emission(AIE).The water-soluble macrocycle without typical AIE luminogens is con-structed based on the building block of benzothiadiazole.It exhibits a remarkable AIE effect.This water-soluble macrocycle can selectively bind different types of biogenic amines in aqueous media with the tightest binding towards spermine.The fluorescence enhancement induced by supramolecular encapsu-lation is used to detect spermine.
