• Summary

    Luminescent metal complexes immobilized in silica nanoparticles will be synthesized and studied. Mesoporous silica nanoparticles (m-SiNPs) are to be synthesized and characterized. Series of luminescent Ru(II)polypyridyl complexes are to be sensitized and characterized. Photophysical properties of these metal complexes will be studied in aqueous and nonaqueous media. Immobilization of these metal complexes in m-SiNPs and NH3-m-SiNPs are to be carried out. Photophysical properties of these fabricated systems are to be studied as well. Excited state decay processes will be followed in the free and bounded form to study the effect of immobilization on the excited state lifetime of the metal complexes. Quenching of the excited state of the free and bounded metal complexes by molecular oxygen are to be studied. Efficiency of these systems as singlet oxygen (excited state molecular oxygen) photosensitizers will be studied. Photooxidation and removal of cyanide effluents by solar irradiation in the presence of the dye-dopped nanoparticles will be assessed. Application to samples collected from cyanide related industrial sites are to be collected and treated.
