  • Pseudorotaxanes, rotaxanes and catenanes formed by metal ions templating
    Patent number: 9085548
    Abstract: A pseudorotaxane, a rotaxane and a catenane are provided. The pseudorotaxane includes at least a macrocyclic host molecule, a guest molecule, and a metal ion. The host molecule contains at least a binding unit and an aromatic linking spacer. The guest molecule has at least a recognition unit. The metal ion is used to template the threading of the guest molecule through the macrocycle host molecule by coordinating to a binding pocket formed from the binding unit of the macrocycle and the recognition moiety of the guest molecule. Rotaxanes or catenanes can be synthesized from the pseudorotaxane complexes, with or without the metal template ion in their molecular structures.

  • Fullerene-containing hemicarceplexes and a method of purifying fullerenes by using the same
    Patent number: 8969594
    Abstract: Fullerene?CTV complexes, comprising fullerene?CTV hemicarceplexes, formed by various cyclotriveratrylene (CTV)-based molecular cages and various fullerene guests are disclosed. A method of direct isolating at least a fullerene from fullerene mixtures by using the above fullerene CTV hemicarceplexes but without using crystallization or HPLC is also disclosed.
