Paper Abstract

During the last decade the interest in polymeric material for second-order nonlinear optical properties has been constantly growing. They combine structural electronic properties, with good thermal and mechanical stability, a relatively low cost and easy processability. The second order nonlinear optical (NLO) properties of such materials have electronic origin, with an ultra-fast response time. In the present paper, we report the preparation and characterization of a new material with a higher concentration of a NLO chromophore. We have synthesized a new dye monomer by the phase transfer catalyzed reaction. We have prepared the copolymer with styrene, by bulk copolymerization; the initiator was di-t-butyl peroxide at 120 degrees C. We have characterized the monomer and the copolymer by IR; UV-Vis; H-NMR spectroscopy. The glass transition temperature and the melting point have been obtained using the differential scanning calorimetry. For studying the NLO properties, the samples have been poled by the Corona poling method, in an electric field of approximately 100V/micrometers . We have appreciated the second- order nonlinear coefficient by comparing the light signal passing through the sample, with the signal passing through a standard quartz plate.
