对氰基苯胺衍生物的合成及SHG效应

SYNTHESIS OF CYANOANILINE DERIVATIVES AND INVESTIGATION OF SHG ACTIVITY

合成了18个对氰基苯胺衍生物，其中13个化合物含有手性原子.测试了它们的旋光度和吸收光谱，含手性原子的化合物均有旋光值，合成产品的最高吸收波长在400～415nm之间．采用固体粉末方法测试了合成化合物的SHG效应，其中8个品种具有SHG活性.经X光衍射分析，探讨了影响SHG效应的有关因素.

Eighteen cyanoaniline derivatives were synthesized and there were 13 compounds having a chiral atom in them.The optical rotation and absorption curves were measured and it was found that the compounds having a chiral atom showed optical activity and the maximum absorption wavelengths of 18 synthesized compounds were between 400 and 415nm.Second harmonic generation(SHG)of synthesized compounds were measured by the powder method and it was found that 8 samples were revealed to possess SHU activity.The influence of the molecular structure on SHG was examined by X-ray crystal analysis.
