摘　　要：合成了 β-硝基四苯基卟啉 [H2 TPP( NO2 ) ]及其锌配合物 [Zn TPP( NO2 ) ],用元素分析、红外光谱、电子吸收光谱等手段对其组成和结构进行了表征。研究了吡啶、4 -甲基吡啶、4 -氨基吡啶、4 ,4 -联吡啶、咪唑、1 -甲基咪唑、2 -甲基咪唑等化合物对 Zn TPP( NO2 )电子光谱的影响。结果表明 ,Zn TPP( NO2 )溶液中加入吡啶类和咪唑类化合物后 ,Zn TPP( NO2 )的电子光谱发生变化是由于 Zn TPP( NO2 )与吡啶类和咪唑类化合物发生轴向配位反应而生成加合物的缘故。A monosubstituted tetraphenylporphyrin and zinc complex (ZnTPP(NO 2)) were synthesized and characterized by elementary analysis, UV and IR spectra. The electronic absorption spectra of axial coordination reactions of ZnTPP(NO 2) with pyridine, 4-methylpyridine, 4-aminopyridine, 4,4-bipyridine, imidazole, 1-methylimidazole and 2-methylimidazole were investigated. The results showed that the changes of electronic absorption spectra of ZnTPP(NO 2) could be attributed to the axial binding of ligands of pyridine and imidazole series to ZnTPP(NO 2) complex.
