Аннотация:The benzo- and thieno-crown ethers containing styryl dyes have been designed and synthesized. The
two series of the compounds were based on different combinations of the oxa- and azaoxa-crown ether
fragments together with 2-benzovinyl- and thienylvinyl-benzothiazolium units. Their complexing, optical
and electrochemical behaviors were characterized, while one and two dimensional NMR was
employed to evaluate the structures of free and complexed ligands. The results of these studies showed
that thienylvinyl derivatives display the poor ability for binding with metal ions through the crown ether
moiety. The phenomenon was explained by the particular charge distribution in thienylvinyl derivatives
preventing the interaction of chromophoric crown ethers with metal ions.
