摘　　要：采用吸收光谱、荧光光谱和皮秒Z-扫描等实验方法研究了两种不同卟啉衍生物5,10,15,20-四苯基卟啉(TPPH2)、5,10,15,20-四对烯基苯基卟啉(T(4-VP)P)和一种金属卟啉配合物5,10,15,20-四苯基卟啉锌(ZnTPP)的线性及三阶非线性光学性质,并根据离域电子共轭结构理论和共振、非共振增强理论对结果进行了分析.The linear and nonlinear optical properties of two porphyrin derivants and a metalloporphyrin complex,TPPH2,T（4-VP）P and ZnTPP respectively,have been investigated by UV-VIS-NIR spectroscopy,fluorescence spectroscopy and picosecond Z-scan technique with 532 nm and 1 064 nm excitation.The optical properties of three samples were discussed based on the theories of л-electron conjugated structures and resonant/non-resonant enhancement,respectively.
