摘要：

In order to search for novel luminescent and EPR oximetry materials, a series of porphyrins and metal loporphyrins 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. (C) 2007 Elsevier Ltd. All rights reserved.
