WebIt should be noted that the α (2 or 5) positions on pyrrole and thiophene and the para (4) position in aniline are the most reactive positions due to inductive and steric factors. Therefore, substitution in the monomer through typical reactions (e.g., SEAr) will attach the substituents to those positions, blocking the oxidative polymerization.
