摘要

In this work, we report the synthesis and properties of TiO_2 and of an organic-inorganic hybrid of TiO_2 where the inorganic network was obtained by hydrolysis (sol-gel process) of the titanium tetraisopropoxide precursor. Both materials were prepared and dried in air. The organic oligomer was synthesized by esterification between ethylene glycol and dipicolinic acid, using Eu~(3+) as probe. These materials were studied by luminescence and infrared spectroscopies, thermogravimetric analysis and X-ray diffraction. The results obtained for the hybrid material show the formation of two crystallinepolymers. Eu~(3+) has been used as structural probe due to its photophysical properties and also as emission center for luminescent materials and the luminescence data indicate that Eu~(3+) occupies one kind of site that is isolated from water molecules and OH groups.
