摘要：

Organophosphorus acids and their derivatives are highly promising coupling molecules that allow the anchoring of organic groups to inorganic solids. In this paper we present the synthesis, by sol-gel method, of organic-inorganic hybrids containing organic phosphonic groups. The obtained hybrid materials were characterized by N(2) adsorption/desorption, IR Spectroscopy, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). IR spectra of the obtained samples show in the 900-1300 region the presence of the vibration typical of phosphonates group. These results suggest the formation of the hybrid network containing Si-O-Si and Si-O-P bonds. TEM, SEM micrographs show mezzo-macroporous materials with high surface area. A low ordered mesoporous structure was evidenced by TEM images.
