Abstract

A new class of nonlinear optical chromophores (NLO-phores) with large off-diagonal components of the second-order polarization and remarkable transparency properties have been investigated. The synthesis and NLO characterization of a series of C2n symmetry benzene derivatives, such as that shown in the Figure, are described. The results of UV-vis, EFISH, hyper-Rayleigh scattering, etc., measurements are compared.
