Tetraphenylethene and Maltoheptaose Conjugate with Aggregation-Induced Emission (AIE) Characteristic for Temperature Sensor

Abstract

The amphiphilic maltoheptaose-tetraphenylethylene (Mal-TPE) was synthesized via copper(I)-catalyzed azide–alkyne cycloaddition (CuAAC) reaction. The as-obtained Mal-TPE conjugate dissolves well in good organic solvent, but can assemble in aqueous medium and exhibit aggregation-induced emission (AIE) effect. The sizes of Mal-TPE aggregrates decrease with the increase in temperature, weakening their AIE effect and resulting in decreased fluorescence intensity. The temperature-dependent fluorescence property of Mal-TPE in aqueous medium can be potentially used in fluorescent thermometry application.
