Abstract

The coordination of pyridine molecules with tetrapyrrole macrocyclic complexes of manganese(III) was studied depending on the ligand structure. The coordination in toluene was ended in all cases in the formation of 1 : 1 complexes, the structure of which was established using MALDI-TOF mass spectrometry and ¹H NMR spectroscopy. The numerical values of the stability constants of the coordination complexes were found to vary from 0.16 to 10⁴ L/mol, depending on the nature of the axial anion in the manganese(III) complex, the structure of the tetrapyrrole macrocycle, and the functional substitution in the macrocycle. The data obtained are useful for selecting the structures in the design of metal porphyrin-based hybrid materials by the immobilization and supramolecular chemistry methods.

锰（III）卟啉与吡啶的配位作为与富勒烯受体形成供体-受体二元组的模型

摘要

根据配体结构研究了吡啶分子与锰(III)四吡咯大环配合物的配位。在所有情况下，甲苯中的配位均以1:1配合物的形成结束，其结构是使用MALDI-TOF质谱法和¹ H NMR光谱法确定的。发现配位络合物的稳定常数的数值在 0.16 至 10 ⁴ L/mol 之间变化，具体取决于锰 (III) 络合物中轴向阴离子的性质、四吡咯大环的结构以及官能团大环中的取代。获得的数据可用于通过固定化和超分子化学方法设计金属卟啉基杂化材料时选择结构。
