Based on the density functional theory (DFT) and using the B3LYP and BMK hybrid exchange-correlation functionals, we have studied the structure and electronic-spectral properties of some triphenylamine oligomers that contain various π-electron spacers of end groups and that are of interest as electro- and photoactive materials. Good agreement between calculation results and experimental data on absorption spectra in the visible and UV ranges has been obtained. The nature of visible spectral bands has been elucidated based on interrelations with structural changes of oligomer molecules.
