Abstract

Abstract : An activity-based Cu 2+ fluorescent probe functions through chelation with Cu 2+ via dye-based multidentate binding, which in turn specifically triggers the probe to undergo hydrolysis to release a NIR emission with AIE + ESIPT properties. Abstract : A novel activity-based Cu 2+ fluorescent probe featuring multidentate binding sites was synthesized. It functions through chelation with Cu 2+, which in turn specifically triggers hydrolysis of the probe to release a near-infrared emission with AIE + ESIPT properties. The probe was found to be capable of ratiometric imaging of Cu 2+ in living HeLa cells.
