| 摘要: 本文合成了几种新型吡啶基修饰的不对称卟啉和金属卟啉，并用核磁、质谱、元素分析、红外光谱、紫外-可见光谱等方法进行了表征，分子模拟研究得到了与光谱分析一致的结果。通过Z-扫描实验对卟啉配合物的非线性光学性质进行了详细研究，这些样品在激光作用下，在532 nm处显示出了强烈的非线性吸收，且取代基位置和金属的不同，均会对三阶非线性折射率的大小产生很大的影响。 |

| Abstract: Several new kinds of asymmetry porphyrins and metalloporphyrins modified by pyridine derivatives were synthesized and characterized by 1H NMR, elementary analysis, MS, IR, UV-Vis spectra etc. Moreover, the results of molecular simulation are consistented with that of spectra analysis. The nonlinear optical properties of porphyrins and metalloporphyrins were studied by Z-scan experiment. Using ns-laser pulse, strong nonlinear absorption is observed at 532 nm. The experimental results show that the effects of different positions of the substituent and different metals on the nonlinear refractivity of the porphyrins are evident. |
