5-芳胺-6-氯2,3-二氰吡嗪的二阶非线性光学活性研究

Study on Nonlinear Optical Properties of 5-arylamino-6-chloro-2,3-dicyanopyrazine

合成了８个５－芳胺－６－氯－２，３－二氰吡嗪新化合物，用溶剂化变色法测定了它们的微观二阶谐波系数和其基态偶极距的复合量，表明它们的微观二阶谐波系数均有较大值。用粉末法测试了它们的宏观倍频效应，它们都具有一定的倍频效应，有可能在这类物质中找到有用的有机非线性光学材料。

Eight novel 5-arylamino-6-chloro-2,3-dicyano pyrazine have been synthesized and characterized.Dealing with solvatochromic method,the composite values of second-order optical polarizabilities (βCT) and the ground state permanent dipole moment (μg) were obtained,all of them are over 205×10-28 esu·D. They all have weak SHG intenties by poweder methods.
