1.Cucurbit[n]uril-based Pseudo-Rotaxane And Polyrotaxane Cotaining Reduced Bis-Schiff Base 2.Inclusion Interaction Between Cyclodextrin And Reduced Bis-Schiff Base Or Alkylcobalt Complexes

Supramolecular chemistry is in the frontier of chemistry. It not only deals with a series of disciplines, such as organic chemistry, coordination chemistry, physical chemistry, biochemistry, environmental chemistry and material chemistry, but also relates to substrate recognition in biological process, selective catalysis and so on. Supramolecular chemistry has developed into Supramolecular science. As two important supermolecular hosts, cucurbit[n]uril(CB[n]) and cyclodextrin (CD) are attracting more and more attention. CB[n]s are a class of pumpkin-shaped macrocycles synthesized by acid-catalyzed condensation of glycolurils and formaldehydes (n = 5~8, 10). CB[n] have large hydrophobic cavities and narrow entries composed by carbonyl-fringed portals, and can recognise some positive ions or include linear amines. On the other hand, CDs are a class of cyclic oligosaccharide molecules normally comprised of six (α), seven (β) or eight (γ)α-1,4 linked D(+)-glucopyranose unite. CDs assume a subulate toroidal shape with hydrophobic interior surface of the cavities and hydrophilic external surface. CB[n]s and CDs are all well known for their ability to form supramolecular compounds or assemblies,...
