The redox and spectroscopic properties of soluble poly‐ (9‐decylcarbazole) derivatives and poly(1‐decylpyrrole) were studied. The polymers were synthesized via the Yamamoto polycondensation method. Analyzing the electrochemical and optical properties of 3,6‐linked poly(alkylcarbazole)s it is evident that the conjugation segment is the benzidine system and the overall properties of these polymers can be compared with meta linked poly(phenylene)s. In opposite, 2,7‐linked poly(alkylcarbazole)s reveal an even longer conjugation segment comparable with para linked poly(phenylene)s. First observations in the case of poly(1‐decylpyrrole) suggest a higher steric hinderance compared to poly‐ (1‐methylpyrrole). Molecular modeling studies confirm this. © 1997 John Wiley & Sons, Ltd.
