A novel clicked tetrathiafulvalene derivative 3 bearing two 8‐oxyquinoline groups was synthesized for the selective detection of Zn 2+ through optical and electrochemical changes. The addition of Zn 2+ and Cd 2+ 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 Zn 2+ were shifted toward more positive values relative to those of the other metal cations tested.
