Abstract
We report the quadratic hyperpolarizability βs of newly synthesized chirals carboxylates salts. These nonlinear optical coefficients have been measured using Hyper-Rayleigh scattering (HRS) technique in solution. Before nonlinear measurements, the different compounds under study were characterized by resonance magnetic nuclear of protons and absorption spectra. They were shown to be completely transparent to the absorption in the UV-Visible and near-infrared region of the spectrum: spectra of solutions in methanol, recorded on an ATI-UNICAM spectrometer in range 250 - 1100 nm show no absorption above 350 - 400 nm. HRS measurements are made by using methanol as solvent and the values of the nonresonant hyperpolarisabilities obtained are of the same order of magnitude that that of the paranitroaniline and are located beween 30x10-30 esu and 60x10-30 esu.
