Abstract

The pore surface of mesoporous MCM-41 type materials have been functionalized with silanes to yield surface bound chelate ligands that include ethylenediamine (ED), diethylenetriamine (DET) and ethylenediaminetriacetic acid salt (EDT). Additionally, The grafted DET ligand was reacted with salicylaldehyde to generate the supported tetradentate Schiff base ligand designated as DES. The MCM-41 bound ligands were used to prepare a series of covalently attached cobalt(II) complexes that potential as oxygen carriers and catalysts. These materials were characterized by FTIR and cyclic voltammetry as well as elemental analysis.
