摘要： 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。

Abstract: The Fourier transform infrared photoacoustic spectra of tetra-(para-methoxyphenyl)porphyrin and its coordination compounds LnT(ρ-CH3O)PPacac(Ln : Sm, Gd, Tb, Dy, Ho,Er, Tm, Yb, Lu)in the range of 3600～225 cm-1 were measured and investigated.Because of the coordination bonding between the rare earth ion and nitrogen in T(ρ-CH3O)PPacac forms,the band near 400 cm-1,M-Ostretching vibration on the acetylacetonate ring,becomes weaker,this band is shifted to the lower wavenumber.The bands at 3318.0 and 968.4 cm-1, PN─H stretching vihration, disppears upon complex formation, the vibration coupling between the M-N stretching and the ring deformation appears.
