The inorganic-organic hybrid material was synthesized by co-condensation of tetraethylorthosilicate and the organosilane N-[3-(trimethoxysilyl)propyl)diethylenetriamine. Spectroscopic analysis of the hybrid material by FTIR showed bands at 2937 and 2839 cm(-1) related to nu(C-H); Si-29 NMR spectrum gave signals at -108, -99, -68 and -59 ppm, Q(4), Q(3), T-4 and T-2 species related to the silica backbone structure. The well-defined peaks obtained in the C-13 NMR spectrum in the 10-58 ppm region confirmed the attachment of organic functional groups as pendant chains bonded into the porous silica. Particle morphology evaluated by a scanning electron microscopic (SEM) study showed the formation of spherical particles in the nanometer range. The...
