Synthesis and characterization of copper(II)-phenanthroline complex grafted organic groups modified MCM-41

The preparation of copper(II)-phenanthroline complex functionalized MCM-41 has been described. The modification of the internal pore surface of mesopo rous MCM-41 with 3-aminopropyl or 3-methacryloyloxypropyl yielded two diffe rent functional groups by using 3-aminopropyltriethoxysilane and (3-methacr yloyloxypropyl)trimethoxysilane as the precursors. Copper(II)-phenanthrolin e complex was grafted onto the functional MCM-41, via the coordination of t he metal ion with the functional groups. The metal ion complex functionaliz ed mesoporous materials were characterized by powder X-ray diffraction, fou rier transform infrared and nitrogen adsorption/desorption at 77 K, as well as electron spin resonance at 293 K.
