为了寻找新型的发光材料和EPR血氧测定材料，合成了一系列外围取代基不同、中心过渡金属离子不同的卟啉和金属卟啉，并研究了它们的紫外-可见光谱、荧光光谱和EPR光谱。结果发现，在外围取代基的变化赋予无金属卟啉的情况下的紫外-可见光谱没有变化。然而，中心过渡金属离子的差异导致电子跃迁能量的变化，从而引起UV-vis光谱的变化。外围取代基和中心金属离子的变化影响荧光和EPR光谱。
In order to search for novel luminescent and EPR oximetry materials, a series of porphyrins and metalloporphyrins with different peripheral substitutes and central transition metal ions were synthesized and their UV–vis, fluorescence and EPR spectra were studied. It was found that variations in the peripheral substituents imparted no change to the UV–vis spectra in the case of metal-free porphyrins. However, differences in the central transition metal ions resulted in changes in the energy of electron transitions which caused changes in UV–vis spectra. Variations in the peripheral substituents and the central metal ions influenced both the fluorescence and EPR spectra.
