线性外源性吡啶吡啶配体,例如1,2-双(4,4'bipyridium)乙烷或其双氧化物衍生物,可用作使用[2]伪the虫的形成的轴24-Crown-8以太(DB24C8)作为车轮。这些[2]假轴可用于使用过渡或灯笼金属离子作为连接节点来构建协调网络。 1-,2-和3D金属 - 有机轮济烷框架(MORF)是可能的。所得的材料包含机械互锁的单元,并且可能是独特固体的先驱,这些固体包含有序阵列中的机器状组件。
Linear exodentate pyridinium ligands such as 1,2-bis(4,4'-bipyridinium) ethane or its bis N-oxide derivative can be used as axles for the formation of [ 2] pseudorotaxanes utilising 24-membered crown ethers such as dibenzo-24-crown-8 ether (DB24C8) as the wheel. These [ 2] pseudorotaxanes can be used to construct coordination networks using transition or lanthanide metal ions as the connecting nodes. 1-, 2- and 3D metal - organic rotaxane frameworks (MORFs) are possible. The resulting materials contain mechanically interlocked units and may be the forerunners of unique solids which contain machine-like components in an ordered array.
