Abstract

Thiophene and pyridine compounds are widely used in medicine, pesticides, and material fields, and study of their physical and chemical changes under an external electric field (EEF) will improve a deep understanding of their properties. In this work, we selected 3-Chlorothieno[2,3-b]pyridine-2-carbonitrile (CPC) as the representative and explored the structure, total energy, dipole moment, Hirshfeld charge, molecular electrostatic potential, infrared, Raman, and UV-Vis spectra of CPC under EEF through density functional theory (DFT). The calculations indicated that the bond length, the bond angle, total energy, dipole moment, and energy gap of CPC are strongly affected by EEF. Infrared, Raman, and UV-Vis spectra showed stark vibration effects with increasing EFF. Our results provide a basis for further applications of CPC with and without EEF.
