Organic anion recognition of naphthalenesulfonates by steroid-modified β-cyclodextrins : enhanced molecular binding ability and molecular selectivity
Two β-cyclodextrin (β-CD) derivatives bearing steroid groups (1 and 2) were synthesized by the condensation of mono(6-aminoethylamino-6-deoxy)-β-CD with cholic acid and deoxycholic acid, respectively, and their original ...
Multirotaxanes with gold nanoparticles as centers
The multirotaxanes with gold nanoparticles as centers are constructed by introducing chromophoric β-cyclodextrin-based rotaxanes on the surface of gold nanoparticles, which show good photophysical and electrochemical ...
Supramolecular assembly of gold nanoparticles mediated by polypseudorotaxane with thiolated β-cyclodextrin
A water-soluble gold nanoparticle aggregate 2 was prepared by chloroauric acid and a polypseudorotaxane 1 of mono-6-thio-β-cyclodextrin with poly(propylene glycol) bis(2-aminopropyl ether) (M ̅_w ≈2000) in the presence ...
