dc.description.abstract | In this computational study, the band gap energy of an acceptor donor type conducting polymer consisting of terthiophene repeating units with a fused bisfulleroid group was estimated by extrapolating excitation energies approximated by the HOMO-LUMO energy differences as well as the TDDFT method with respect to the inverse number of monomer units. Optimizations were performed both in vacuum and in o-dichlorobenzene (as solvent) using the B3LYP and MPW1B95 functionals. The calculated optical band gap was found to be in good agreement with experimentally reported band gaps in the literature. However, different band gaps with different experimental techniques were reported in the referred experimental study for the same system. To understand the reasons behind this behavior, effects of the structural (inter- and intramolecular stacking) and environmental (explicit and implicit solvation and acidic doping) factors on the absorption of the terthiophene monomer with fused bisfulleroid were investigated. Acid doping was found to be very important in terms of the present system. | en_US |
