亚甲基桥联杯[4]芳烃作为一种非常通用的配体载体，在形成具有迷人磁性的新型多金属簇合物方面有着广泛的应用。金属离子结合规则建立了这个积木允许一个部分合理化的复杂的组装过程。在亚甲基桥处共价连接杯[4]芳烃的能力提供了对将不同金属中心引入所得簇基序的显著改进的控制。由双杯[4]芳烃和过渡金属离子或3d-4f组合组装的簇显示类似杯[4]芳烃负载簇的特征，从而证明了复杂和具有挑战性结构的靶向合成的增强和合理的方法。
Methylene-bridged calix[4]arenes have emerged as extremely versatile ligand supports in the formation of new polymetallic clusters possessing fascinating magnetic properties. Metal ion binding rules established for this building block allow one to partially rationalise the complex assembly process. The ability to covalently link calix[4]arenes at the methylene bridge provides significantly improved control over the introduction of different metal centres to resulting cluster motifs. Clusters assembled from bis-calix[4]arenes and transition metal ions or 3d-4f combinations display characteristic features of the analogous calix[4]arene supported clusters, thereby demonstrating an enhanced and rational approach towards the targeted synthesis of complex and challenging structures.
