Of particular interest, the dimeric pseudo[1]catenane, named &lsquo;gemini-catenane&rsquo;, contained stereoisomeric meso-erythro and dl-threo isomers, in which two P[5]A moieties are threaded by two DA-n chains in topologically different patterns. This access to chiral pseudo[1]catenanes and gemini-catenanes will greatly promote the practical use of such sophisticated chiral architectures in supramolecular and materials science and technology.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/ncomms8590 Authors: Shenghua Li, Heng\u2010Yi Zhang, Xiufang Xu, Yu Liu Abstract: Mechanically interlocked and entangled molecular architectures represent one of the elaborate topological superstructures engineered at a molecular resolution.
