Abstract New crown ether styryl dyes containing various heterocyclic moieties and substituents were synthesized. Thecis andtrans isomers of crown ether styryl dyes and their complexes with metal cations were characterized by their absorption and fluorescence spectra. Based on an analysis of the spectral parameters and the shifts of the absorption and fluorescence maxima upon photoisomerization and complexation, the effects of the nature and structure of the heterocyclic moiety on the photochromism of styryl ionophores were revealed.
