综述了在磁场作用下进行的一系列卟啉化合物的光谱研究，重点介绍了这些化合物的分子功能。综述了分子磁光效应，如克尔效应、磁手性二色性(MCHD)和时间分辨电子顺磁共振(TREPR)。本文描述了一种新型的分子磁光存储器，该存储器是基于硅酞菁与铁磁衬底耦合的克尔光谱研究结果。讨论了低对称性四氮杂卟啉衍生物的TREPR分析结果，以确定分子对称性与单线态氧产量之间的关系，因为了解这种关系对于光动力学治疗是必不可少的。最后，介绍了一种新的解释生物体系中不对称性的方法--卟啉分子轨道密度法。此外，它还可以导致新的不对称合成方法，并为新型磁光器件奠定基础。
The spectroscopies of a range of porphyrinic compounds performed under a magnetic field are reviewed, focusing on the molecular functions of the compounds. Characteristic molecular magneto-optical effects, such as the Kerr effects and magnetochiral dichroism (MChD), as well as time-resolved electron paramagnetic resonance (TREPR) are reviewed. A novel molecular magneto-optical memory is described on the basis of the results of a Kerr spectroscopic study of Si phthalocyanine coupled with a ferromagnetic substrate. The results of TREPR analyses of low-symmetry tetraazaporphyrin derivatives are discussed in order to determine the relationship between molecular symmetry and singlet oxygen yield, as knowing this relationship is essential for photodynamic therapy. Finally, the MChD of porphyrins is introduced as a new way of elucidating the asymmetry in biological systems. Further, it can lead to new asymmetric synthesis methods and form the basis for novel magneto-optical devices.
