The immobilization of two different succinic-modified carboxy-imide-porphyrins on the surface of amino-modified SBA-15 is reported. The SBA-15 was synthesized and modified by reacting its hydroxyls groups with the OH and/or OR groups of 3-amino propyl triethoxy silane, anchoring the amino group on its surface. Separately, two different derivatives amino-porphyrins (NH2-5-m-Etio-III–Ni2+ and NH2-2βpyrrolic-m-5,10,15,20-TPP–Ni2+) were modified using succinic anhydride to provides these with the carboxyl group appropriate to react covalently with the amino groups previously anchored on the SBA-15; these new hybrid materials have the appropriated textural and chemical characteristics to be used in heterogeneous catalysis. The samples were characterized by XRD, N2 adsorption isotherms, HR-TEM, TGA/DTA, FTIR, UV/VIS, 13C and 29Si NMR-CP/MAS.
