Theoretical estimations of dynamic first hyperpolarizability of D-π-A chromophores with fused (azinylmethylene)malononitrile macroacceptors
DFT study of nonlinear-optical chromophores Q′, QPh, PP1 and Qon with fused (azinylmethylene)malononitrile macro-acceptors (azine is quinoline, quinoxaline, pyridopyrazine and quinoxaline-2-one) is performed. Small effect of conformation on the first hyperpolarizability, β, values is demonstrated. The solvent effect on the molecular polarizabilities is considered by the example of dioxane and dichloromethane both for static and dynamic cases. The ratios of β(2ω) for the cases solvent/gas increase gradually in a series Q′, QPh, PP1 and Qon correlating with azine moiety aromaticity decrease. The highest β(2ω), 2655⋅10−30 esu, is obtained for Qon in dichloromethane.
