Abstract
3-Amino-2-(2-nitrophenyl)diazinyl-3-(morpholin-1-yl)acrylonitrile (ANMA) has been successfully synthesized via conventional solvent method, and its molecular structure has been identified by using various techniques including FTIR, 1H NMR, MS and elemental analysis. The crystal structure of ANMA is characterized by single crystal X-ray crystallography. Crystallographic data revealed that the spatial structure of ANMA belongs to monoclinic, P21 a space group. ANMA thin films were deposited onto optical flat quartz substrates by using thermal evaporation under vacuum pressure of 2×10−4Pa. The optical properties of the films are studied in terms of the measurements of transmittance and reflectance determined at the normal incident of light over the spectral range 200–2400nm. The absorption coefficient of the films is computed and the optical band gap of the films is estimated. In addition, the complex refractive index for the films has been calculated and described. Single oscillator model is found to be applicable for the films in which the dispersion parameters namely; single oscillator energy, dispersion energy, dielectric constant at high frequency, lattice dielectric constant and the ratio of carrier concentration to the effective mass are estimated.
