Abstract
Summary: N‐Hexyl‐cyclopenta[c]pyrrole was synthesized and electrochemically and chemically polymerized to a novel 1,3,4‐alkyl‐substituted polypyrrole. The polymer was characterized in solution and as thin solid film by cyclic voltammetry, UV‐vis, FTIR and NMR spectroscopy, MALDI mass spectroscopy, GPC analysis, electrochemical quartz crystal microbalance, ESR spectroscopy and in situ conductivity. The polymer, with a defect‐free structure and an average degree of polymerization of 13 (electrochemically prepared) and 24 (chemically prepared), is soluble (>1%) in acetone, acetonitrile and chlorinated solvents. Its in situ conductivity as a function of potential and doping charge has the typical features of redox conductivity with a maximum value of ca 1 × 10^−3^ S · cm^−1^.
