| 摘要: 本文合成了一种新型Boc(叔丁氧羰基)保护手性苏氨酸修饰的自由卟啉及其锌配合物。通过元素分析、紫外-可见光谱、荧光光谱、核磁共振氢谱、CD光谱等多种谱图对结构进行了表征，并结合理论计算采用模拟退火的方法搜索了手性锌卟啉配合物的最低能量构象。此外，利用Z-扫描技术测定了手性卟啉化合物的三阶非线性折射率。 |

| Abstract: A chiral Zn porphyrin complex was synthesized and characterized by means of elementary analysis, UV-Vis, Fluorescence spectrum, CD spectrum and 1H NMR. The result of CD spectroscopy shows that the coupling between the electric moments of the chiral amino acid and those of porphyrin chromophores leads to the symmetrical Cotton effect. And then, the minimum energy conformation of chiral zinc porphyrin complex is obtained by simulated annealing, and zinc ion is projected from the plane of porphyrin ring and the chiral side chain is over the plane of porphyrin ring. Moreover, the third-order nonlinear optical properties of the chiral zinc porphyrin complex were studied. The nonlinear refractive index of the chiral zinc porphyrin complex was measured with nanosecond laser pulses at 532 nm by Z-scan techniques. |
