摘要：
Poly-dibenzo-18-crown-6 ether (poly-DB18-C6) is synthesized under its p-doped state by electrochemical oxidation of dibenzo-18-crown-6 ether. This polymer may possess complexing properties towards metallic cations especially when used under its neutral state (after undoping process). This publication deals with the complexing properties of poly-DB18-C6 with the monovalent silver cation. Various factors influencing this complexation are studied, in particular, the reduction process of the polymer and then the time of contact of cation and polymer, the concentration of silver solution, the solvent, etc.
