The fluorescent probe TPE-Py was designed and synthesized, and its structure was confirmed by NMR and HRMS. The recognition properties of probe TPE-Py for metal ions have been studied through fluorescence spectrophotometry and cell imaging experiments in HeLa cells. The results showed that TPE-Py had good selectivity and sensitivity for Cu2+. Among various metal ions, TPE-Py only showed exclusive fluorescence turn-off sensing on Cu2+ in H2O/THF (VV=9∶1). The results of cell imaging experiments showed that the probe TPE-Py could detect Cu2+ in lipid droplets of cells.

Key words: aggregation-induced emission, fluorescent sensor, ion recognition, cell imaging
