Abstract
The quadratic hyperpolarizabilities of a series of pyridinium and quin olinium salts are measured by hyper-Rayleigh scattering in solution. T hese salts present high hyperpolarizabilities combined with good trans parencies in the visible region of the spectrum. The higher efficiency of the teraryl over the biaryl for the conjugation path between the d onor and the acceptor groups is clearly evidenced.
