Use of polymeric resin in the formation of SiO2 hybrid gels

New organic-inorganic hybrid material with interpenetrating polymer networks was synthesized with a phase of SiO2 made by sol-gel chemistry and an organic phase made from a polymeric resin obtained by polyesterification between metal chelate complexes and a polyfunctional alcohol. One modification i...

Description
Summary:New organic-inorganic hybrid material with interpenetrating polymer networks was synthesized with a phase of SiO2 made by sol-gel chemistry and an organic phase made from a polymeric resin obtained by polyesterification between metal chelate complexes and a polyfunctional alcohol. One modification in this method consists in preparing organic polymers doped with Eu III/dipicolinic acid or Tb III/1,2-phenylenedioxidiacetic acid complexes. Eu and Tb luminescent properties were used as a probe to obtain structural information about the hybrid gel. To the organic polymers authors added tetraorthosilicates to obtain transparent and luminescent organic-inorganic hybrid materials through the sol-gel process. Luminescent and ir spectra and thermogravimetric properties were measured. 27 refs.
