5-（4-硝基苯基）-10，15，20-三苯基卟啉及其金属配合物的合成与光谱性质

硝基取代的卟啉是合成生物活性分子的有效单体．有广泛的应用价值。它的合成是重要的研究课题。由于硝基的强吸电子性．使硝基苯基卟啉的合成难度加大。本文以四苯基卟啉（TPP）为原料．通过硝化反应合成了5-（4-硝基苯基）-10，15，20-三苯基卟啉，并进一步合成了其金属配合物（Mn，Zn）。利用紫外可见光谱、红外光谱、核磁共振氢谱．对合成产物进行了结构表征，对不同产物的紫外、红外谱图进行了对比分析。与卟啉配体相比，金属卟啉的分子对称性有所提高，吸收峰的数目相应减少。

Synthesis and Spectra of 5-(4-nitrophenyl)-10,15,20--triphenylporphyrin and its metallic aggregates

Nitro-substitued porphyrins is a useful synthetic precursors to biologically activemolecules.Study on its synthesis is of extensive interest.But,the difficulty of nitro-substitued porphytrins is enhanced due to strong absorb-electonics of nitro band.This paper describes 5-(4-nitrophenyl)-10,15,20-triphenylporphyrin synthesized by regioselective nitration of the phenyl groups of meso-tetraphenylporphyrin with metallic aggregates.The structures of the porphyrins is characterized by UV-Vis spect rum(UV),infrared spectrum(IR) and()~1HNMR.The UV-Vis and IR of the different outcomes are compared.It reveals that symmetries of the metallic particles is improved and the number of absorbent is decreased in comparison with the porphyrins.
