【摘要】 概述了近年来用1 HNMR表征一些四取代酞菁金属配合物异构体的研究进展情况。四取代酞菁配合物存在 4种异构体和 8种磁不等价的异吲哚基。这些磁不等价的异吲哚基对苯环上以及取代基的质子的1 HNMR谱均有所影响 ,因此可以通过测定这些质子的1 HNMR谱来确定异构体。更多还原

【Abstract】 The recent progress was presented briefly on the characterization method of the isomers of tetra-substituted~ metal phthalocyanines by 1H NMR. The tetra-substituted metal phthalocyanines were constituted~ by four isomers and eight magnetically nonequivalent isoindole units, which exert an influence on the protons of both the aromatic ring and substituted groups. Therefore, the symmetry of isomers can be confirmed by analysis of the 1H NMR spectra of these protons.更多还原
