杯[4]芳烃是一种多功能配体，当与3d，4f金属离子反应时，能形成多种簇合物。在杯[4]芳烃亚甲基桥的合成修饰提供了一个独特的机会，探索与这些替代的构建块的簇形成。在这里，我们提出了一系列的双杯[4]芳烃的烷基链，以及探索性的结构研究成簇反应的合成。在四种情况下形成单晶体，并且从阐明的X-射线结构可以得出结论，足够长的烷基系链允许在不破坏核心配位化学的情况下形成已建立的簇拓扑结构。
Calix[4]arenes are versatile ligands capable of forming a wide range of cluster motifs when reacted with 3d, 4for 3d/4fmetal ions. Synthetic modification at the calix[4]arene methylene bridge offers a unique opportunity to explore cluster formation with these alternative building blocks. Here, we present the synthesis of a range of bis-calix[4]arenes that are tethered by alkyl chains, as well as exploratory structural studies into cluster-forming reactions. Single crystals were formed in four cases, and from the X-ray structures elucidated it is possible to conclude that sufficiently long alkyl tethers allow for the formation of established cluster topologies without disruption to the core coordination chemistry.
