The big pore size characteristic of molecule sieves such as MCM-41 and the silanol hydroxyl group which is subject to alkylation made it possible to synthesize ligands in the pores of the moleucle sieves, and then to chelate with metal ions to form solid-support metal compexes. This is among one of the most active field in the development of pore-mediated molecule sieves catalysts. For example, Schiff-Mn(III)complexes, Ruhenium-porphyrin complexes, chiral Salen-Mn(III)complexes, Cr(III)-binaphthyl Schiff base complexes linked to Mcm-41 all showed better activity and selectivity in the cyclooxidation of olefins, depicting an iceberg of it's application prospect.

Based on the macroporous structure and "alkylable" nature of silanol groups of MCM-41 and other molecular sieves, it was possible to synthesise ligands within the tunnels of those molecular sieves. With subsequent chelation with metal ions, the complexes formed were anchored on a solid phase. This methodology has also become one of the most intensively researched field in the development of pore-mediated molecule sieves catalysts. For example, embedded Schiff-Mn(III)complexes, Ruthenium-porphyrin complexes, chiral Salen-Mn(III)complexes, Cr(III)-binaphthyl Schiff base complexes in Mcm-41 all showed better efficiency and selectivity in the epoxidation of olefins, showing great promise in its future applications.
