A fluorescent ionophoric compound is disclosed that includes a complexing moiety, such as a cryptand or crown-ether portion, and a fluorescing moiety such as a coumarin portion. The coumarin portion may be substituted at the 3-position with an electron withdrawing or polarizable group such as a substituted aromatic group or a substituted heterocyclic group having a heteroatom in at least one of its alpha positions. The compound, which exhibits good photostability, can be incorporated into cation-sensing composite structures by means of convenient points of covalent attachment.
