测定了中位(meso)取代八乙基卟啉和无轴向配位卟啉锌(Ⅱ)配合物的结构,讨论了锌离子配位前后卟啉环的平面性,并比较了有锌和无锌配位卟啉阴离子的几何构型。研究结果表明卟啉骨架的构型不仅决定于卟啉骨架中央孔穴的大小,配位离子的尺寸和电子结构,而且还决定于骨架上的取代基团。本文还分析了在卟啉骨架上取代硝基的几何构型以及它们在卟啉共轭效应中的作用。
The structures of meso-substituted octaethylporphyrin and the uncoordinated porphyrin zinc (Ⅱ) complexes were determined. The planarity of the porphyrin rings before and after coordination of zinc ions was discussed. The zinc and Geometric Configuration of Zinc - free Porphyrin Anions. The results show that the configuration of the porphyrin skeleton depends not only on the size of the central pore of the porphyrin framework, the size and electronic structure of the coordination ion, but also on the substituent groups on the backbone. In addition, the geometrical configurations of the substituted nitro groups on the porphyrin framework and their roles in the porphyrin conjugation are also analyzed.
