Hybrid mesoporous SBA-15silicas were synthesized directly with variable alkylazide loading representing 2-50% surface coverage. These hybrid silica materials retain the favorable physical attributes of the parent SBA-15 materials and allow efficient covalent attachment of ethynylated organic moieties through a copper catalyzed 3 + 2 Huisgen cycloadditionreaction. Three distinctly different examples
