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.
Claims4
A metal colloid formed by a process comprising performing a reaction on 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;
- wherein the reaction is selected from pyrolysis, thermal decomposition, oxidative decomposition and a combination thereof.
