Abstract

A variety of pyridinium and benzothiazolium-substituted conjugated donor-π-acceptor dipoles are studied by hyper- Rayleigh scattering (HRS) in solution. We have investigated their potential as strong electron acceptor moiety and a complete series has been synthesized and characterized. An elongation of the conjugated π-system for each molecule is made and characterized to see the influence of the elongation of the conjugated π-system. A leveling off of the hyperpolarizability β is already observed after three subsequent double bonds.
