Abstract
Novel styryl dyes containing dithia-15(18)-crown-6(5)-ether moieties w ere synthesized. Their selective complex formation with Hg2+ and Ag+ i ons was studied by (0)1H NMR and electronic spectroscopy; the stabilit y constants of the Ag+ complexes and the relative stability constants (in relation to benzodithia-18-crown-6) of the Hg2+ complexes were det ermined. The chemical shifts of the beta,beta'-protons in the CH2S gro up change upon the complex formation in parallel with the logK(1) valu es of the complexes.
