摘　　要：非线性光学材料在激光、光通信、光处理、高频电光器件及太赫兹等方面具有重要的应用。相比传统无机非线性光学材料,有机二阶非线性光学材料具有电光系数高、响应速率快、易加工等优点。近年来,基于有机非线性光学材料的研究成为热门领域,高频电光器件、太赫兹器件等都受到了业内广泛关注。本文综述了不同种类的有机二阶非线性光学材料的研究进展和未来的发展方向。此类材料的电光性能和取向稳定性可以通过分子设计策略和化学合成、发色团与聚合物的结构关系及掺杂技术等进行有效的调控,但是研发满足实际应用且综合性能优异的有机非线性光学材料仍面临诸多挑战。Nonlinear optical materials play a very important role in some advanced technology areas such as laser, optical communication, optical processing, high-frequency electro-optic devices and terahertz(THz) areas. Compared with the traditional inorganic materials, organic second-order nonlinear optical materials have the advantages of high electro-optic coefficient, fast response as well as easy processing. Recently, the research focusing on organic nonlinear optical materials and devices has been a hot area, especially the high-frequency electro-optic modulators and THz devices have received extensive attention. This review systematically describes the research progress in recent years and future development directions in the field of organic second-order nonlinear optical materials. The electro-optic properties and orientation stability of materials can be effectively turned through molecular design strategies and chemical synthesis, structural relationship between chromophores and polymers and doping techniques. However, there are still many challenges in developing organic nonlinear optical materials with excellent properties to meet the requirements of practical applications.
