四(对-十二酰氧基苯基)卟啉配合物的红外光声光谱

The fourier transform infrared photoacoustic spectra ofmeso-tetra-(4-lauroyloxyphenyl)porphyrin(TLPPH2) and its complexes with Mn (Ⅲ)、Fe (Ⅲ)、Co (Ⅱ)、 Ni (Ⅱ)、Cu (Ⅱ) and Zn (Ⅱ) in the range of 3600～190 cm-1 were measured and investigated. The bands at 3318 and 968 cm-1 of TLPPH2 are due to the N—H stretching and in-plane and out of plane bending vibration of the pyrrole groups. All these bands disappear upon complex formation. The vibration coupling between the M—N stretching and the porphyrin ring deformation appears at 250 cm-1. Metal sensitive bands were found at 1354、1018、983、796、736、632、231 cm-1.

5,10,15,20-四(对-癸酰氧基)苯基卟啉过渡金属配合物的红外光声光谱

测试并研究了 5,1 0 ,1 5,2 0 -四 (对 -癸酰氧基 )苯基卟啉及其 Mn( )、Fe( )、Co( )、Ni( )、Cu( )、Zn( )配合物在 360 0～ 1 90 cm- 1范围内的傅立叶变换红外光声光谱 ,对主要谱带进行了经验归属。结果表明 :331 8,968cm- 1处的吸收谱带分别是四 (对 -癸酰氧基 )苯基卟啉 N-H键伸缩振动、面内弯曲振动 ,生成配合物后这些谱带全部消失。 2 50 cm- 1处的吸收谱带是 M-N键伸缩振动和卟啉环变形振动的复合振动 ,32 7cm- 1处的吸收谱带是 M-Cl键伸缩振动 ,金属敏感带出现在 1 354、1 0 1 8、991、790、632、2 31 cm- 1 处。
