The synthesis and single-crystal X-ray diffraction structure of a dimeric zinc-seamed nanocapsule using a mixed pyrogallol/resorcinol[4]arene are presented. The use of "mixed" macrocycles results in an incomplete seam of coordination bonds around the nanocapsule's typically octa-metalated belt. The self-assembly of the nanocapsule occurs such that the single resorcinol moiety of each macrocycle aligns transversely. This yields a hepta-metalated capsule where the defect occurs in such a way as to provide minimal disruption to the overall structure of the nanocapsule.
本文报道了一种使用混合焦棓酚/间苯三酚[4]芳烃合成的二聚锌缝合纳米胶囊及其单晶 X 射线衍射结构。使用“混合”大环导致纳米胶囊通常八配位的金属带周围的配位键缝合不完全。纳米胶囊的自组装使得每个大环的单个间苯三酚部分横向对齐。这产生了一个七配位的胶囊，其中缺陷的发生方式对纳米胶囊的整体结构造成的破坏最小。
