The synthesis and first hyperpolarizabilities of a series of isoquinolines and isoquinolinium salts, and also thienopyridines, thienylpyridines, and the corresponding pyridinium salts, determined by hyper-Rayleigh scattering in solution at 1064 and 1300 nm, are reported. These chromophores exhibit markedly high β values. Some of them show absorption maxima well below 400 nm, enabling their use in blue transparent frequency doubling devices. We have performed X-ray structure analyses for thienopyridines 13a,c.
