Abstract
The invention provides complexes in which ligands (e.g., calixarene-related compounds) are coordinated to a metal colloid, e.g. a gold colloid. In exemplary embodiments, two or more ligands complexed to the metal colloid are larger than the metal colloid, thus providing an accessible metal center. The complexes can be immobilized on a substrate. The complexes of the invention are useful as tunable and highly robust isolated metal colloids that find use in binding of molecules and catalysis of chemical reactions.
Claims55
A complex comprising:
- (a) a metal colloid comprising three or more metal atoms;
- and
- (b) two or more ligands, each ligand comprising a linker, wherein the linker comprises a coordinating atom coordinated to one of the metal atoms
- wherein at least two of the ligands are larger than the metal colloid.
