自从富勒烯被发现以来，[1]映射到C60表面的碗状聚芳烃引起了人们的广泛关注。[2]这些测地富勒烯片段或“巴基碗”代表了一类令人兴奋的新型芳香配体，具有独特的化学性质。[2f]最近，人们大力研究巴基碗的反应性和连接特性，但分离出的过渡金属配合物却很少。[3, 4]去年，我们最终成功地制备了第一个测地聚芳烃晶体配合物，采用升华沉积技术在无溶剂环境下具有最小的碗状多环芳烃，corannulene（1，C20H10，图1）。[4]晶体学数据的可用性使我们能够确定金属与这种开放测地聚芳烃的弯曲不饱和碳表面结合的优选位点，以及多达三个金属原子与 Corannulene 边缘碳原子的 η2 配位
Since the discovery of fullerenes,[1] bowl-shaped polyarenes that map onto the surface of C60 have attracted considerable attention.[2] These geodesic fullerene fragments or “buckybowls” represent an exciting new class of aromatic ligands that exhibit unique chemistry.[2f] Substantial efforts have recently been directed toward studies of the reactivity and ligating properties of buckybowls, but very few of their transition metal complexes have been isolated.[3, 4] Last year, we finally succeeded in preparing the first crystalline complexes of a geodesic polyarene, using the sublimation–deposition technique in a solvent-free environment with the smallest bowl-shaped polycyclic aromatic hydrocarbon, corannulene (1, C20H10, Figure 1).[4] The availability of crystallographic data allowed us to determine the preferred sites for metal binding to the curved unsaturated carbon surface of this open geodesic polyarene, and η2 coordination of as many as three metal atoms to the rim carbon atoms of corannulene
