Bis(molecular tube)s: Supramolecular Assembly of Complexes of Organoselenium-Bridged β-Cyclodextrins with Platinum(IV)

A novel supramolecular assembly, bis(molecular tube)s composed of complexes of organoselenium-bridged β-cyclodextrins and platinum(IV) ion, have been fabricated via the pseudorotaxane with poly(propylene glycol) and characterized by 1H NMR, TEM, and AFM images, etc.
