macropentacyclic compounds (1)–(3), which combine porphyrin rings and [18]-N2O4aza-oxamacrocycles as substrate selective bindingsubunits, complex diammonium ions +H3N–[CH2]n–NH3+(anchored to the [18]-N2O4sites and included in the central molecular cavity) and /or ZnIIions (bound to the porphyrin groups), thus yielding organic/inorganic mixedsubstrate supramolecular structures.
结合卟啉环和[18] -N 2 O 4氮杂-氧杂大环作为底物选择性结合亚基的大环和大五环化合物(1)-(3),复杂的二铵离子+ H 3 N- [CH 2 ] n -NH 3 +(锚定在[18] -N 2 O 4位并包含在中心分子腔中)和/或Zn II离子(结合到卟啉基上),从而产生有机/无机混合底物超分子结构。
