本文报导了三种邻位取代四苯基卟啉衍生物[H_2T(O-NO_2)PP。H_2T(O-NH_2)PP。H_2T(O-NHR′)PP(简称PN_4,R′=-COC_5H_4N)]及其五种配合物[(acac)L_n(Ⅲ)P.acac为乙酰丙酮阴离子,L_n(Ⅲ)为Eu(Ⅲ)和Yb(Ⅲ),P为卟啉]的合成,紫外可见光谱、荧光发散光谱,红外振动光谱、~1HNMR谱的测定及用群论和HMO法对其共轭体系的计算。由实测光潜、波谱数据和用HMO法计算的“八轨道模型”说明自由碱卟啉分子具有D_(2h)对称性,配合物中主配体属于C_点群,配合物的电子吸收光谱是由配体卟啉环共轭体系产生的。
In this paper, three ortho-substituted tetraphenylporphyrin derivatives [H_2T (O-NO_2) PP] have been reported. H_2T (O-NH_2) PP. (Acac) L_n (Ⅲ) P.acac is acetylacetonate anion, L_n (Ⅲ) is Eu (Ⅲ) And Yb (Ⅲ), P is porphyrin], UV-vis spectra, fluorescence emission spectra, infrared vibration spectra and ~ 1HNMR spectra were calculated and their conjugate systems were calculated by using group theory and HMO method. The measured optical potential, spectral data and the “eight-orbit model” calculated by HMO method show that the free alkali porphyrin molecule has D 2h symmetry. The main ligand in the complex belongs to the C_point group. The electron of the complex The absorption spectrum is generated by the ligand porphyrin ring conjugation system.
