Abstract
Chemical synthesis and concentration dependence of two second order NLO tensor components: and was studied for a side chain polymer PMMA-DR1 in thin films by optical second harmonic generation techniques. The noncentrosymmetry was created by the corona poling technique. The results show that for small chromophore concentrations the susceptibility follows linearly the density number of active chromophores, reaches a maximum, than decreases and stabilizes.
