A simple and rapid functionalization of MOF via microwave-assisted one-pot synthesis afforded a Cu(ii)-Schiff-base-MOF as an efficient catalyst for olefin oxidation.

Microwave irradiation is exploited for the facile, onestep functionalization of Cu(acac) 2 to -NH 2 pendant groups of MIL-53(Al)-NH 2 , a metal-organic framework material, under mild reaction conditions and a short reaction time. PXRD, XPS, XAS, and EPR spectroscopy are used to investigate the structure and chemical nature of the copper species on the framework. The copper center exists in the +2 oxidation state with a square-planar geometry and NO 3 coordination environment. The copper complex is anchored to the framework by imine bond formation. This copper-functionalized MIL-53(Al)-NH 2 or [a
