P, Registration Date 24-01-2012 Organization A.V.Bogatsky Physico-Chemical Institute of the National Academy of Sciences of Ukraine popup.description2 Objects of research: polymer and hybrid organosilicon materials, doped with lanthanide containing complexes with luminescence in IR-region on the base of acyclic (polydentate complexones and beta-diketones) and macrocyclic (porphyrins and calix[4]arenes, modified with fragments of carboxylic acids) ligands. Objective of research: development of methods of synthesis of nanoparticles on the base of homo- and heteronuclear lanthanide complexes with polydentate ligands of different types doped in silica matrix and polymeric carriers, study of structural characteristics and basic factors of the influence on the photophysical characteristics of the systems obtained. Methods of synthesis of polymeric and hybrid organosilicon materials doped with lanthanide containing complexes, luminescent in the IR-region, based on acyclic (nitrogen-and phosphorus-containing polydentate complexoes and beta-diketones with unsaturated substituents) and macrocyclic (porphyrins and calix[4]arenes modified with fragments of carboxylic acids) ligands were developed. Silica nanoparticles with homo-and heteronuclear complexes of lanthanides, which are binding on the silicate matrix by both covalent and noncovalent interactions were synthesized by sol-gel method, optimal conditions for obtaining monodispersed nanosystems have been found. Analysis of the photophysical properties of lanthanide containing silica nanoparticles was made and influence of the structure of luminescent unit was investigated, photo-and chemical stability of the systems was researched.
