摘要: 本文研究了四(对-硝基苯基)卟啉及其Cr(Ⅲ)、Mn(Ⅲ)、Fe(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)配合物的3500220cm-1的红外光谱和1700100cm-1的拉曼光谱.谱带归属表明,250cm-1谱带是M—N伸缩振动和卟啉环变形振动的复合振动.金属敏感带出现在1600、1582、1547、1284、1190、355和245cm-1处,其中二价金属配合物金属敏感带频率按Ni>Co>Cu>Zn顺序递减.用金属半径和dx2-y2电子排斥作用解释了金属敏感带变化规律.

Abstract: The Infrared spectra(220-3500 cm-1)and Raman spectra(100-1700 cm-1)of te-tra(p-nitrophenyl)porphyrin and its Cr(Ⅲ),Mn(Ⅲ),Fe(Ⅲ),Co(Ⅱ),Ni(Ⅱ),Cu(Ⅱ)and Zn(Ⅱ)complexes were measured and investigated respectively.The band at 3321 cm-1 and 988 cm-1 belonging to N-Hvibrations of pyrrole disappears when the complex formed.The metal sensitive bands were found at ~1600,~1582,~1547,~1284,~1190,~355 and ~245 cm-1.The bands at 355 and 245 cm-1 of the complexes decrease in wave number in the order of Ni(Ⅱ)>Co(Ⅱ)>Cu(Ⅱ)>Zn(Ⅱ).The bands at ~3110,~1600,~1520,~1350,~850 and ~825 cm-1 resulted from p-nitrobenzene of the porphyrin.
