摘要：

A new class of cross-linked second-order nonlinear optical (NLO) polymers has been developed by processing a NLO-dye and a polymer similar to conventional 'doped polymer' system. Intermolecular cross-linking was carried out by UV radiation subsequent to electric field induced poling of the composite. Cinnamate (C6H5-CH = CH-CO2-) and styrylacrylate (C6H5-CH = CH-CH = CH-CO2-) moieties are selected as the photoreactive chromophores which are attached to both the NLO molecules at two positions and randomly substituted to a vinyl polymer. The poled cross-linked polymers exhibit stable nonlinear activity over a long period of time as characterized by temporal response of second-harmonic generation signal and UV absorption characteristics.
