[5]Rotaxane,linear polymer and supramolecular organic framework constructed by nor-seco-cucurbit[10]uril-based ternary complexation

Here we use nor-seco-cucurbit10]uril (ns-CB10]) based ternary complexation to construct 5]rotaxane, linear supramolecular dynamic rotaxane polymers and cubic 3D supramolecular organic framework. A 5]rotaxane is constructed by ns-CB10], TMeCB6] and short linear derivatives of 4,4′-bipyridinium (M2). ns-CB10], CB7] and long linear derivatives of 4,4′-bipyridinium (M3) self-assemble into a linear supramolecular dynamic rotaxane polymer. ns-CB10] and tetracationic tetrahedral monomer self-assemble and form a three-dimensional supramolecular organic framework. The above results demonstrate that ns-CB10]-based ternary complexation is a versatile platform to build various supramolecular systems.
