Abstract

Thin films of 4-tricyanovinyl-N,N-diethylaniline (TCVA) were prepared for the first time using thermal evaporation technique. The molecular structure and electronic transitions of TCVA films were investigated by Fourier-transform infrared (FTIR) and ultraviolet–visible (UV–vis) spectra. The observed vibrational wavenumbers in FTIR spectra were analysed and assigned to different normal modes of the molecule. UV–vis electronic absorption spectral measurements of TCVA films were analysed to obtain the electronic transitions and optical band gap (Eg). Other important optical parameters such as molar extinction coefficient (ɛmolar), the oscillator strength (f), and the electric dipole strength (q2) were also reported.
