摘　　要：设计合成了一种以均三嗪为核,苯乙烯基、氮碳双键共轭键为桥,羟乙氧基为供电子基团的八极分子,用IR、EA、1H MNR、UV-Vis和DSC-TG等对其结构和性能进行了表征,采用粉末倍频法对其二阶非线性光学性能进行了测试.实验表明:在N,N-二甲基甲酰胺(DMF)中该八极分子的最大吸收波长为411.5 nm,热分解温度为397℃,倍频效应强度为磷酸二氢钾(KDP)晶体的1.7倍,具有较好的热稳定性和透明性,可用于制备性能优异的非线性光学材料.An octupolar molecule with triazine as core, styryl conjugate and nitrogen-carbon double bond as bridge and hydroxy ethoxy as the donor group was designed and synthesized. The structures and properties of the organic molecules were characterized by IR, elemental analysis, ^1H MNR, UV-Vis and DSC-TG. The second order nonlinear optical properties was determined by Kurtz-Perry powder method. The results show that the compound second-harmonic generation （SHG） equals to 1.7 times of potassium dihydrogen orthophosphate （KDP）. The maximum absorption wavelength of the compound was 411.5 nm. The compound was thermally stable with the decomposition temperature of 397℃. Consequently it could be considered to be a better choice for the preparation of nonlinear optical （NLO） materials.
