Notes:
Anodic coupling of the dihydrobenzodipyrrole isomers 1H,8H-pyrrolo[3,2-g]indole (1), 1H,7H-pyrrolo[3,2-f]indole (2), and 1H,5H-pyrrolo[2,3-f]indole (3) in 0,1 M tetraethylammonium perchlorate in acetonitrile produces polymeric films which are reversibly oxidized around 0,3 V vs. Ag/Ag+ with 0,5 electrons per monomeric unit. IR reflectance, UV-vis and cyclic voltammetry show that the oxidized polymers undergo easy overoxidation at the benzene ring without affecting the charge storage ability. Conductivities (0,2-5 Ω-1 · cm-1) are higher than those presented by chemically prepared samples (10-4 - 10-1 Ω-1 · cm-1) and are attributed to more ordered structures of the polymers.
