Abstract

The Energy gap, HOMO and LUMO energies, Ionization Potential, Electron Affinity, Dipole Moment, and Mean Polarizabilities of Polythiophene, (PT) Polyisothianaphthene (PITN), and Polythiophene-polyisothianaphthene (PT-PITN) copolymer were determined. Using these molecular properties, it was concluded that doped PT-PITN copolymer with six monomeric units exhibits the highest conductivity, as indicated by the low HOMO−LUMO energy gap, and high mean polarizability, the resulting doped polymer was also found out to be stable, as indicated by the very low total energy.
