The heteroaryl- and heteroarylenevinylene compounds 1, 2, 3, and 4 were investigated by means of cyclic voltammetry and submitted to oxidative electropolymerization under galvanostatic conditions; the products obtained were further characterized by means of elemental analysis, optical absorption spectroscopy and conductivity measurements. (E)-1,2-bis(N-methyl-2-pyrrolyl)ethylene (1), 2,5-bis[(E)-2-(N-methyl-2-pyrrolyl)vinyl]thiophene (2) and N-methyl2,5-bis[(E)-2-(N-methyl-2-pyrrolyl)vinyl]pyrrole (3) gave brittle to spongy films on electropolymerization with perchlorate as the counterion balancing the positive charge on the polymer backbone units. The d. c. conductivity of all three polymers (as perchlorates) was of the order of 10-3 Ω-1·cm-1. N-methyl-2,5-bis[(E)-2-(2-thienyl)vinyl]pyrrole (4) did not give a solid polymer.
