New Magnetic Phosphonate Organic-inorganic Hybrid Materials

The synthesis and the characterization of new phosphonate organic-inorganic hybrid materials obtained by the incorporation of the monoazoic acid dyes (C1, C2, C3, C4) into a titanium dioxide phosphonate matrix is described in this study. The hybrid materials were obtained by simple sol-gel method and their morphology prooved to be different depending on Ti/P ratio and of molecular structure of the incorporated dye. Furthermore, iron oxide magnetic nanoparticles (MNPs) were also incorporated in the above-mentioned matrix. The presence of phosphorus could be observed in all organic-inorganic hybrid materials. The obtained hybrid materials present good mechanical, chemical and optical properties and for these reasons they are very attractive candidates for different applications in fields like environmental chemistry or photo catalysis. Moreover, the materials containing MNPs are specially intriguinig due to their advantage of easy separation from the reaction media by simple magnetic decantation increasing thus the reusability of this type of system.
