Abstract

8-Hydroxyquinoline ligands 1 and 2 as fluorescent chemosensors for zinc or cadmium ions were synthesized. It is generally difficult to selectively respond to Zn²⁺ over Cd²⁺ or Cd²⁺ over Zn²⁺. However, ligand 1 selectively responded to Zn²⁺ over Cd²⁺, and ligand 2 selectively responded to Cd²⁺ over Zn²⁺.
