ELECTROACTIVE MATERIALS CONTAINING MACROCYCLIC PSEUDO-CROWN ETHER CAVITIES ELECTROFORMED FROM A SOLID-STATE ELECTROPOLYMERIZATION REACTION

New compounds consisting of two different electropolymerizable aromati c groups (pyrrole/thiophene 1, pyrrole/dimethoxybenzene 2, and dimetho xybenzene/thiophene 3) linked together by a polyether subunit have bee n synthesized and their electrochemical behavior has been investigated . At relatively low anodic potential values, the oxidation of these mo nomers led to electroactive homopolymer films containing pendant aroma tic moieties. The oxidation of the preformed polymers by applying more positive potentials promoted further anodic couplings within their st ructure. The efficiency or this solid-state electropolymerization reac tion was found to be strongly dependent on the film thickness. So, ele ctroactive copolymers possessing controllable size pseudo-crown ether cavities were thought to be obtained.
