Abstract

The electrochemical polymerization of new pyrrole-substituted tetrathiafulvalenes (TTF) bearing thiol, sulfonyl, and disulfide groups has been studied. The repeated electrochemical oxidations of its TTF-pyrrolylthiol (1) on a glassy carbon electrode gave the modified electrode, however, the surface coverages of electroactive TTF moieties in the film did not increase with increasing number of repeated electrochemical cycling. In contrast to 1, TTF-pyrrole-sulfone (2) and -disulfide (3) undergo electropolymerization to form the multilayer films onto metal electrodes, in which the surface coverages were increased by increasing number of repeated potential cycling.
