Abstract
This paper describes the preparation of manganese(II)-phenanthroline complex functionalized MCM-41 (MCM from Mobil Crystalline Material). The as-synthesized organic group functional MCM-41 and metal-ion-complex functionalized MCM-41 were extensively characterized by powder X-ray diffraction (XRD), TEM, solid-state 29Si and 13C NMR and nitrogen adsorption/desorption isotherms at 77 K, as well as Mn(II) electron spin resonance (ESR) spectroscopy at room temperature. These results indicated that 3-methacryloyloxypropyl group well dispersed in the mesopore of MCM-41, which attached to the silicate walls via Si–O–Si bonds. The mesopore of MCM-41 was tailored by the grafted organic group and the complex, while the coordination state of Mn(II) was unaffected by the process of grafting.
