Paper Abstract

Two stilbene derivatives, DANS and CNDS, were synthesized. The optical properties of organic doped PMMA poled polymer films were investigated with in situ second-harmonic generation (SHG) measurement and UV-visible absorption measurement. Optimum corona poling temperatures of the polymer films were studied. The second-order susceptibility (chi) (2_ of CNDS/PMMA is larger than that of DANS/PMMA, although CNDS molecules in PMMA is less ordered than DANS. The molecular second-order polarizability (beta) of the CNDS was estimated to be about 1.4 X 10-28esu. The relaxation of SHG intensity of CNDS/PMMA was slower than that of DANS/PMMA. It is concluded that CNDS is a better dopant than DANS as second-order nonlinear-optical material.
