New dicyanovinyl-substituted 1-(alkyl)aryl-2-(2'-thienyl)pyrroles 2 were synthesized and characterized. The solvatochromic behavior of thesynthesized compounds was investigated. All the derivatives showed reversible oxidation and reduction on the CV time scale. Thehyperpolarizabilities (mages/gifchars/beta2.gif" BORDER=0 ALIGN="middle">) of compounds 2 were measured using hyper-Rayleigh scattering. The results are among the highest mages/gifchars/beta2.gif" BORDER=0 ALIGN="middle"> values reportedfor donor-acceptor-substituted thienylpyrroles.
