Abstract
Anodic coupling of the three isomeric dihydrobenzodipyrroles (1)-(3) produces polymeric films the conductivities of which (0.2–5 S cm−1) are higher than those presented by chemically prepared samples (10−4 -10−1 S cm−1). Results are reported also for the three dimethyl homologues (4)-(6). Comparison of conductivity data and behaviour of the methyl substituted (4)-(6), allow us to conclude that the sites involved in the polymerization of (1) are the α pyrrolic positions.
