| 摘 要： | 通过芳胺与芳醛的缩合反应，合成了１２个希夫碱系有机化合物。测试了它们的紫外－可见吸收曲线，结果表明：１２个希夫碱系有机化合物的最高吸收波长都在紫外区内。随着芳环（Ａ）取代基供电性的增加，芳环（Ｂ）取代基吸电性的增加，希夫碱系有机化合物的吸收波长红移。采用固体粉末方法测试了合成产品的ＳＨＧ效应，结果发现其中４个品种具有ＳＨＧ活性。

| Abstract: | organic compounds of Schiff bases have been synthesized by the condensation of aromaticamine and aromatic aldehyde.The absorption curves of UV-visible have been measured and it isfound that their maximum absorption wavelength are all in the ultraviolet region.The absorptionwavelength of Schiff bases com pounds cause red shift with increasing the donor electron ofsubstitute group on the aromatic amine ring and the acceptor electron of substitute group on thearomatic aldehyde ring.Second harmonic generation of synthesized compounds have beenmeasured by the powder method and it is found that 4 samples have been revealed to possessSHG activity. |
