Abstract
Some new heterocyclic chromophores have been synthesized by greenway method. These chromophores have been evaluated by analysing their solvatochromic properties and molecular optical nonlinearities. Their hyperpolarizability (β) has been calculated theoretically. The non-zero tensor components of the imidazole derivatives reveal that they possess potent non-linear optical (NLO) behaviour. Measurements of absorption solvatochromism have been interpreted with Marcus and Reichardt–Dimroth solvent functions to estimate the transition dipoles. Good correlation exists between absorption as well as fluorescence wavenumbers obtained by the multi-component linear regression employing the Taft and Catalan solvent parameters with the experimental values.
