Abstract

Herein, the design of a novel aggregation-induced emission (AIE) supramolecular fluorescence sensor (TA-PEGn) based on a tridentate melphalan derivative and three different molecular weight PEGs is presented. The three TA-PEGn sensors could self-assemble into a supramolecular system in water and show sensitive and selective responses toward trinitrophenol.
