The research on organic nonlinear optical （NLO） materials containing cyanoes-group is attracting more and more attention. Studies on the synthesis of these NLO materials show the evolution of conjugated chains longer, molecule structure more complex and multi-dimensional. As the techniques maturing, molecule modifications about device application are concerned and these applications have fabricated to devices in industry fields. In this paper, researches on the synthesis of these materials are reviewed. Technologies of synthesizing high electro-optical activity and low optical loss NLO materials are discussed. The future development of molecule design of NLO materials is also commented.
