摘　　要：合成了几种卟啉单体和卟啉二聚体,并测定了它们的三阶光学非线性的吸收系数(β)、折射率(n2)以及极化率(χ(3)),对比研究了卟啉周边取代基及桥连基团的不同对三阶光学非线性的影响.实验结果表明非线性极化率随卟啉大环电子云密度的增加而增大.Several porphyrin monomers and porphyrin dimers were synthesized and their third-order optical nonlinearities were determined. Different peripheries of the porphyrin macrocycle and bridging groups had influence on third-order optical nonlinearities. Experimental results confirmed that the nonlinearities polarization rates increased along with the enhancement of electron density of porphyrin macrocycle.
