Abstract
The invention provides complexes in which a calixarene-related compound is coordinated to an iridium-containing metal colloid. 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.
Claims42
A complex comprising:
- (a) a metal colloid comprising a plurality of iridium atoms;
- and
- (b) a calixarene-related compound comprising a linker, wherein the linker comprises a coordinating atom coordinated to one of the plurality of iridium atoms.
A method of synthesizing a calixarene-bound metal colloid, the method comprising contacting a calixarene-related compound with a colloidal metal bromide under conditions appropriate to cause bromide anion displacement from the colloidal metal bromide.
