Styryl-based NLO chromophores: synthesis, spectroscopic properties, and theoretical calculations

摘要: A novel series of styryl-based chromophores is synthesized, the constituents which are characterized by UV–Vis, NMR, mass spectrometry, and thermal analysis. The show good solubility in MeOH, THF, CH2Cl2. They also stability for practical applications. Density functional theory calculations employed order to ascertain structural, molecular, electronic properties dyes. Moreover, second nonlinear optical (NLO) responses dyes measured electric field induced harmonic (EFISH) generation method. Relatively high scalar products vector component first hyperpolarizability tensor dipole moment (μβ) obtained some compounds.
