ABSTRACT:
A fluorescent ionophoric compound comprises a cryptand portion and a coumarin portion substituted at the 3-position with an electron withdrawing or polarizable group. The compound, which exhibits good photostability, can be incorporated into cation-sensing composite structures useful in biological and environmental testing, which can be used with conventional glass optics, by means of convenient points of covalent attachment.
