Double chromophore complex system and its synthesis method and application

Abstract

The present invention relates to an organic / polymer electro-optic material, and particularly relates to a double chromophore complex system and synthesis and application thereof. The double chromophore complex system is a mixture of a side chain type subject chromophore-containing main polymer or a Y type subject chromophore-containing main polymer and an object chromophore, wherein the molar ratio of subject chromophore to object chromophore is 1:1. The growth rate of the electro-optic coefficient of the double chromophore complex system in the molar ratio is obviously superior to the growth rate of the electro-optic coefficient of the double chromophore complex system in other molar ratio. In the optimum molar ratio, the electro-optic coefficient of the double chromophore complex system can be increased to the greatest degree, by dissolving the double chromophore complex system in an organic solvent and coating, the biggest electro-optic coefficient of a prepared polarized electro-optic polymer film is 160pm / v. Therefore, the prepared polarized electro-optic polymer film can be used as an optical material, and can be applied to an electro-optic modulator, an optical sensor, an optical converter, and information transmission and other aspects.
