The Electronic and Nonlinear Optical properties of the donor-acceptor molecules 2-(4-aminophenyl) Quinoline, 4-(4-aminophenyl) Quinoline, Anthraquinone; and the molecules Anthracene and Phenanthrene have been determined and some of these properties compared with literature values. The theoretical calculations were performed at the RHF level of theory and with two different hybrid density functional theories (DFT) (B3LYP and B3PW91), using the 6-31 +G** basis set. The results show that these molecular systems have large average polarizability, anisotropy and first molecular hyperpolarizabilities. The small values of epsilon, and LUMO-HOMO energy band gap (E-gap) and the high values chi, eta, < alpha >, and (beta(mol)) show that the molecules have very good electronic, nonlinear optical, optoelectronic and photonic applications. Furthermore, the (E-gap) of Phenanthrene shows that Phenanthrene is a good promising organic superconductor material.(C) 2016 Published by Elsevier B.V.
