The synthesis of a new triaminoguanidinium-based ligand with three tris-chelating [NNO]-binding pockets and C symmetry is described. The reaction of tris-(2-pyridinylene-N-oxide)triaminoguanidinium salts with zinc(II) formate leads to the formation of cyclic supramolecular coordination compounds which in solution bind fullerenes in their spherical cavities. The rapid encapsulation of C can be observed by NMR spectroscopy and single-crystal X-ray diffraction and is verified using computation.
描述了一种新的三氨基胍基配体的合成，该配体具有三个三螯合[NNO]结合口袋和 C 对称性。三-(2-吡啶基亚胺-N-氧化物)三氨基胍盐与甲酸锌反应生成环状超分子配位化合物，在溶液中，这些化合物将富勒烯包裹在其球形空腔中。通过 NMR 光谱和单晶 X 射线衍射可以观察到 C 的快速包裹，并用计算进行了验证。
