Sp. Gromov et al., CROWN-CONTAINING STYRYL DYES .14. SYNTHESIS, LUMINESCENCE, AND COMPLEXATION OF THE TRANSISOMERS OF CHROMOGENIC 15-CROWN-5-ETHERS, Russian chemical bulletin, 44(10), 1995, pp. 1922-1928
Novel crown ether styryl dyes containing heterocyclic residues with va
rious substituents were synthesized. The fluorescence and absorption s
pectra of the trans-isomers of crown ether styryl dyes and their compl
exes with metal cations were studied. Based on spectral data, the infl
uence of the nature of a heterocyclic residue, the crown ether fragmen
t, and the temperature on the fluorescence of dyes and their complexes
with metal cations was elucidated.
