Abstract
We use a quantum chemical approach to investigate the chemical and electronic structure of polydithieno[3,4-b;3′,4′-d]thiophene (PDTT′), for which the monomer unit possesses four potential linking sites on α carbon positions. Semiempirical Austin Model 1 (AM1) calculations are performed on oligomer systems, considering different types of connection between the DTT′ units, to determine the most favorable chain conformation and the relative stabilities of the oligomer segments. The electronic properties of the corresponding polymers are calculated with the Valence Effective Hamiltonian (VEH) method and compared to the results of optical spectroscopy.
