A simple heterogeneous synthesis of pure modified porous polysiloxane SiO 2 by condensing a functionalized C,C ‐pyridylpyrazole with a 3‐glycidoxy‐propyltrimethoxy‐silane silylant agent, previously anchored on a silica surface is reported. The epoxide group was opened yielding a receptor pendant group bonded to the inorganic surface. The surface modification (MS) was characterized by elemental analysis, infrared spectra, nitrogen adsorption–desorption isotherm, BET surface area and B.J.H. Pore sizes. The new material exhibits good chemical and thermal stability determined by thermogravimetry curves. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
