Abstract

[structure: see text] New dicyanovinyl-substituted 1-(alkyl)aryl-2-(2'-thienyl)pyrroles 2 were synthesized and characterized. The solvatochromic behavior of the synthesized compounds was investigated. All the derivatives showed reversible oxidation and reduction on the CV time scale. The hyperpolarizabilities (beta) of compounds 2 were measured using hyper-Rayleigh scattering. The results are among the highest beta values reported for donor-acceptor-substituted thienylpyrroles.
