New cavitand derivatives (1, 2) bearing four coumarin groups were synthesized, and the binding properties of these cavitands towards metal ions were examined through their fluorescent changes. Cavitand 1 effectively recognized the Cu2+ ions among the metal ions examined. The recognition of cavitand 1-Cu2+ with dicarboxlyates is also described.
