ResumoAbstract Novel acyclic and cyclic monoazapolythioether derivatives incorporating a substituted hydrazone group were synthesized. The acyclic and the cyclic monoazatetrathioether derivatives exhibited high Ag+ ion selectivity in the extraction with 1,2-dichloroethane. The monoazatetrathioether derivatives gave hypsochromic and bathochromic shifts in the visible absorption spectra when extracted Ag+ ion from the aqueous phase of varying acidities into the organic phase.
