Organometallic complexes pore loading

Chart 4 Examples of organometallic complexes that can be pore-loaded in MOF-5... 

The best way to control the nuclearity of metal clusters is to trap them in the calibrated pores of zeolites. The production of clusters encaged in zeolites has been described in a recent review [5]. Metal loading is carried out either by ion exchange and reduction or by adsorption and decomposition of organometallic complexes. If these treatments are performed under proper conditions, the clusters can be obtained at precise locations in the zeolite micropores, which impose an upper limit on the cluster size. Thus in faujasite-type zeolites, the supercages can accommodate up to 60 metal atoms.
