研究了乙酰丙酮－ｍｅｓｏ－四－（对－甲氧基）苯基卟啉及其Ｓｍ、Ｇｄ、Ｔｂ、Ｄｙ、Ｈｏ、Ｅｒ、Ｔｍ、Ｙｂ、Ｌｕ配合物在３６００～２２５ｃｍ－１范围的付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，由于四－（对－甲氧基）苯基卟啉与稀土金属离子配位，削弱了乙酰丙酮环上的Ｍ－Ｏ键的伸缩振动，使此谱带向低波数移动。配合物中ＰＮ－Ｈ伸缩振动谱带消失，出现Ｍ－Ｎ伸缩振动与卟啉环变形振动等的复合振动。
The effects of acetylacetone-meso-tetrakis (p-methoxy) phenylporphyrin and its complexes of Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu on the range of 3600 ~ 225cm-1 Leaf transform infrared photoacoustic spectroscopy, the main spectral bands have been attributed. The results show that due to coordination of tetrakis- (p-methoxy) phenyl porphyrin with rare earth metal ions, the stretching vibration of M-O bond on the acetylacetone ring is weakened and the band shifts to a low wavenumber. The complex disappears in the stretching vibration band of PN-H, resulting in complex vibration such as M-N stretching vibration and porphyrin ring deformation vibration.
