Periodic Mesoporous Organosilica Derivatives Bearing a High Density of Metal Complexes on Pore Surfaces

Periodic mesoporous organosilica derivatives (PMOs) that bear a high density of Ru and Ir complexes on pore walls were synthesized using a unique two-step approach: 1) synthesis of PMO containing phenylpyridine bridging groups in the pore walls, and 2) post-synthetic formation of metal complexes using the phenylpyridine groups as chelating ligands (see picture).
