| 摘 要： | 采用固体粉末方法，测试了苯系偶氮、嘧啶、吡啶酮、四氢喹啉甲川型染料，以及中间体共６２个有机分子的ＳＨＧ效应，发现其中１４个品种具有ＳＨＧ活性。考察了影响ＳＨＧ效应的有关因素，发现电子效应基本一致的硝基和氰基取代染料，呈现出完全不同的ＳＨＧ性质。说明电子效应并不是影响有机分子ＳＨＧ活性的唯一因素，ＰＰＰ－ＭＯ理论计算结果也证实了这点。

| Abstract: | Activities of optical second harmonic generation for 62 synthesized compounds, which are the azo dyes based on phenyl derivatives, aminopyrimidine, pyridone and methine dyes of trimethyl-tetrahydroquinoline as well as their intermediates, have been measured by the powder technique using YAG laser. It is found that 14 samples have been revealed to possess second harmonic generation activity. The influences on SHG are investigated and found that the dyes with substituents of nitro and cyano group have shown different SHG activities. It indicates that the influence of the electronic effect on SHG activity is not the only factor. It is also proved by PPP-MO calculation results. |
