摘　　要：利用酐为原料合成出N,N′-二(间羟基苯基)二酰亚胺,再通过与TDI(2,4-甲苯二异氰酸酯)的共聚合成了具有酰亚胺单元的P-π共轭聚合物,利用IR、UV-Vis、元素分析和热重分析对其结构进行了表征。并利用四波混频方法测定了该聚合物的三阶非线性,其响应系数达1.39×10-13esu,响应时间为132.59fs。另外,测得其溶液具有较高的荧光发射强度。N,N-diresorcyl perylene diimide(PTAD) was synthesized by perylene-3,4,9,10-tetracarboxylic acid dianhydride and m-amino phenol with zinc acetate as catalyzer. A new type of polymer with perylene element was prepared by PTAD and TDI. The product owns improved solubility and film-forming quality. All the product structures were characterized by IR, UV-Vis and elemental analysis. The third-order non-linear optics of the polymer was measured by degenerated four-wave mixing(DFWM) technique and the coefficient χ~^((3)) of the polymer is as high as (1.39)×10^(-13) esu. The Response time of the polymer is (132.59) fs. The Fluorescent intensity was measured by Fluorescence Emission Spectrograph and the Fluorescent Intensity is very high.
