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

FOURIER TRANSFORM INFRARED PHOTOACOUSTIC SPECTRA OF TRANSITION METAL COMPLEXES OF TETRA (4-p-DECANOYLOXYPHENYL) PORPHYRIN COMPLEXES

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。

The fourier transform infrared photoacoustic spectra of transition metal complexes of meso tetra (4 lauroyloxyphenyl) porphyrin TDPPH 2 and its Mn(Ⅲ)、Fe(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ) and Zn(Ⅱ) complexes in the range of 3600～190cm -1 were measured and investigated.The bands at 3318 and 968cm -1 of TDPPH 2 are due to the N H stretching and in plane and out plane bending vibration of the pyrrole groups.All these bands disappear upon complexes formation.The vibration coupling between the M N stretching and the porphyrin ring deformation appears at 250cm -1 .The band at 327cm -1 is due to M Cl stretching vibration.Metal sensitive bands were found at 1354、1018、991、790、736、632、231cm -1 .
