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.
