在大量的Co、Ni、Pd和Pt卟啉配合物上进行了荧光光谱。用处于氧化态I、II和III的金属检查Co络合物。在任何情况下，激发光谱都没有证实Co或Ni络合物发光，在最纯的样品中，磷光产率的上限为φp< 0.0005。Pd和Pt络合物强烈磷光，产率在0.2和0.9之间。寿命，产量和振动峰的报告。钯卟啉和铂etioporphyrin的产量被发现是相对温度无关的溶剂的熔点。Pd和Pt的原卟啉在脱气的室温液体中都发磷光。钯卟啉主磷光带分裂在低温烷烃溶液中，两个峰的温度依赖性表明，它们产生的激发态的几何形状的变化。
Luminescence spectra were taken on a large number of Co, Ni, Pd, and Pt porphyrin complexes. The Co complexes were examined with the metal in oxidation states I, II, and III. In no case have excitation spectra confirmed that a Co or Ni complex luminesce, and in the purest samples an upper limit of phosphorescence yield isφp< 0.0005. Pd and Pt complexes phosphoresce strongly with yields between 0.2 and 0.9. Lifetimes, yields, and vibrational peaks are reported. Yields of Pd porphin and Pt etioporphyrin are found to be relatively temperature independent up to the melting point of the solvent. Both Pd and Pt etioporphyrins phosphoresce in degassed room temperature liquids. The Pd porphin main phosphorescence band is split in low temperature alkane solution; the temperature dependence of the two peaks suggests that they arise from a geometry change in the excited state.
