A mechanically interlocked [2]rotaxane is reported incorporating a ditopic ligand moiety as one of the stoppers. Upon complexation with palladium(ii) ions a metallo-[5]rotaxane was formed with a porous Pd2L4 metal-organic cage at the core of the structure. This proof-of-principle system precedes work towards the construction of metal organic polyhedra with switchable mechano-chemical properties.
据报道，一种机械互锁的[2]轮烷包含一个双齿配体部分作为封端剂之一。与钯（II）离子络合后，形成了一种金属[5]轮烷，其结构核心为多孔的Pd2L4金属有机笼。这个原理验证系统为构建具有可切换机械化学性质的金属有机多面体的研究奠定了基础。
