摘　　要：合成了一种手性基团修饰的金属卟啉化合物[5-对(L-亮氨酰氧乙氧基)苯基-10,15,20-三苯基卟啉锌].通过元素分析、紫外可见光谱、红外光谱、圆二色光谱及核磁共振波谱对该化合物进行了较详细的表征.同时,采用分子力学方法搜索了主体的最低能量构象,从理论上进一步解释实验结果.利用Z扫描技术测定了该化合物的三阶非线性光学性质.One kind of novel chiral Zn porphyrin was synthesized. By means of elementary analysis, UV-Vis, IR, CD spectrum, and ^1H-NMR, the chiral Zn porphyrin was charactered. The lowest energy conformation of the chiral zinc porphyrin was obtained by system search on the basis of Tripos force field. Nonlinear optical properties of the chiral porphyrin complexes were studied and refractive indexes were measured by Z-scan techniques. The result indicates that chiral zinc porphyrin has biggish nonlinear refractive index. This is an effective method by modifying chiral structure of porphyrin complexes to increase nonlinear refractive index.
