Key Points

  • The research aims to explore how substituting S atoms with N–CH3 groups in thiophene–phenylene oligomers affects their properties.
  • Analyzed optical and electronic properties of isolated molecules.
  • Examined charge transport in thin films of the modified oligomers.
  • Conducted comparative studies on S and N-substituted structures.
  • Found changes in optical properties due to N-substitution.
  • Demonstrated improved charge transport in thin films with N–CH3 groups.
  • Revealed modified optoelectronic characteristics in the studied oligomers.

Abstract

We address the impact of the substitution of S atoms by N–CH 3 groups in a thiophene–phenylene co-oligomer DPBTBT, on the optical and electronic properties of isolated molecules and the charge transport and optoelectronic properties in thin films.
