New organic-inorganic hybrid materials G1-G5 were obtained by chemical reaction of polymethylhydrosiloxane (PMHS) and bi-functional heterocyclic molecules under 2:1 stoechiometry, in tetrahydrofurane as solvant, using hexachloroplatinic acid (H2PtCl2, 6H2O) as catalyst at 60 °C. This reaction leads to the formation of transparent and monolithic gels. The xerogels have been caracterized by infrared, 29Si and 13C CP MAS NMR spectroscopy. The results show the formation of Si–N; Si – O; Si – S bridges in produced xerogels. The thermal analysis of the xerogels was determined by TGA and DTA. Xerogels morphology and texture of the obtained materials were studied by scanning electron microscopy (SEM) and Brunauer – Emmet – Teller method (BET).
