摘　　要：设计、合成了两个新的咪唑类二阶非线性光学生色团 ,对其热性能、透明性和二阶非线性光学性能进行了测定和研究 ,实验表明生色团为非线性光学性能 -透明性 -热稳定性能综合优化的有机二阶非线性光学生色团 .Two conjugated donor-acceptor imidazole derivatives for second-order nonlinear optics were designed and synthesized. The thermal properties, the transparency and second-order nonlinear optical properties of these chromophores were investigated. Experimental results indicate that a good nonlinearity-transparency-thermal stability trade-off was achieved for them.
