Abstract


With the advent of the information age , the high-speed optical communications , optical information processing and optical storage has achieved rapid development and application prospects of nonlinear optical materials in the field has also been more and more attention . Nonlinear optical materials research focuses on the design and development of the synthesis of a variety of new chromophore dipole molecules and macro asymmetric organic polymer films , organic-inorganic hybrid nonlinear optical film preparation , chromophores oriented film stability is one of the most talked about issues . This paper from the structural design of the novel organic polymer asymmetric membrane , the electric field-induced assembly method to prepare a multilayer light having a crosslinked structure stable second order nonlinear optical film materials , and this novel electric field induced assembly method is extended to organic - inorganic hybrid second-order nonlinear optical film material , the material is more stable , the assembled film thickness can be improved , the material is therefore closer to the practical . Further, in order to solve the limit of the electric field-induced assembly method on the substrate selection , containing the negative charge of the polymer is spin coated on the insulating substrate as a lower cladding layer , and directly on the cladding layer have been assembled by the film material , the thus obtained material may be directly for the preparation of the photovoltaic device . Tablet polarization , the electric polarization at room temperature to prepare a high - quality organic - inorganic hybrid film material having a light- crosslinked structure . In addition, simple operation , simple siloxane dye molecules with a \
