Abstract

A novel clicked tetrathiafulvalene derivative 3 bearing two 8-oxyquinoline groups was synthesized for the selective detection of Zn2+ through optical and electrochemical changes. The addition of Zn2+ and Cd2+ induced a significant change in fluorescence intensity, which was attributable to the chelation-enhanced fluorescence effect from the oxyquinoline and 1,2,3-triazole rings. The electrochemical potentials of 3 in the presence of the Zn2+ were shifted toward more positive values relative to those of the other metal cations tested.
