A review is presented of our contribution addressed towards: i) the control of redox potentials of pyrrole- and thiophene-based conductors and ii) the search for polythiophene models. We approached the first by exploiting the spacer strategy, according to which the monomer contains two terminal polymerogenic units linked to a central π-conjugatively active frame. The second topic was approached by investigating end-methyl-capped thiophene oligomers. Taken together, the results clear up many puzzling aspects and provide influential clues for designing tailored heterocyclic structures that respond to specific operational requirements
