含手性原子硝基苯胺衍生物的合成及SHG效应

有机非线性光学材料具有ＳＨＧ活性高、响应时间快、分子结构可变性等优点。合成了２０个含不对称原子氨基酸取代的苯系化合物，测试了这些化合物的旋光度、紫外一可见吸收、ＳＨＧ效应，发现１７个化合物具有ＳＨＧ活性，初步探讨了影响ＳＨＧ效应的有关因素。

SYNTHESIS AND SECOND HARMONIC GENERATION EFFECT OF NITROANILINE DERIVATIVES WITH CHIRAL ATOM

Abstract Twenty N-2,4-dinitropbenyl amino deriva-hves were svnthesized from 2,4-dinitrofluo-robenzene and amino acid,and purified by recrys-tallization. The compounds were confirmed bymeans of m.p.,thin-layer chromatography,MSand UV absorption in ethanol. The results indi-cated that their λ_(max) were between 338nm and373nm,and that the substituting groups had ef-fects on UV absorption spectra. Measured by thepowder method, sixteen samples in the twentycompounds showed SHG activities.
