Subnanometer-sized Gold Clusters with Dual Molecular Receptors: Synthesis and Assembly in One-dimensional Arrangements

Subnanometer-sized gold clusters protected by thiolated β-cyclodextrin (HS-β-CD) were successfully isolated using polyacrylamide gel electrophoresis. Thermogravimetric measurements reveal that two β-CD ligands are bound to the Au clusters. One-dimensional assemblies of the β-CD-modified gold cluster...

Zusammenfassung:Subnanometer-sized gold clusters protected by thiolated β-cyclodextrin (HS-β-CD) were successfully isolated using polyacrylamide gel electrophoresis. Thermogravimetric measurements reveal that two β-CD ligands are bound to the Au clusters. One-dimensional assemblies of the β-CD-modified gold clusters are formed through binding interactions with ferrocene dimers.
