Abstract

Graphical abstract: Highlights: A novel series of styryl-based chromophores was synthesized and characterized. The chromophores showed good solubility in MeOH, THF, and CH2 Cl2, and good thermal stability for practical applications. Relatively high μβ values are obtained for some of the compounds. Abstract: A novel series of styryl-based chromophores is synthesized, the constituents of which are characterized by UV–Vis, NMR, mass spectrometry, and thermal analysis. The chromophores show good solubility in MeOH, THF, and CH2 Cl2 . They also show good thermal stability for practical applications. Density functional theory calculations are employed in order to ascertain the structural, molecular, and electronic properties of the dyes. Moreover, the second order nonlinear optical (NLO) responses of the dyes are measured by the electric field induced second harmonic (EFISH) generation method. Relatively high scalar products of the vector component of the first hyperpolarizability tensor and the dipole moment vector ( μβ ) are obtained for some of the compounds.
