摘要：
Silanation of the internal pore surface of the mesoporous molecular sieve MCM-41 (40 Angstrom) has yielded ethylenediamine (ED), diethylenetriamine (DET); and ethylenediaminetriacetic acid salt (EDT) functionalized sites. These grafted ligands were used for the preparation of cobalt(II) complexes covalently bound to the MCM-41 support. These materials were characterized by SEM, UV-vis, FTIR, ESR, and cyclic voltammetry as well as elemental analysis. Preliminary studies suggest the formation of a reversible cobalt-oxygen adduct with MCM-41 grafted ED and DET. The nature and reactivity of the MCM-41 bound complexes were found to differ significantly from functionalized amorphous silica.
