Objective of research - development of efficient methods for obtaining of heteronuclear lanthanide compounds and p-metals with nitrogen-and phosphorus-containing complexones, calix[4]arenes, modified with fragments of complexones, methods of synthesis of silica nanoparticles containing homo- and heteronuclear complexes of lanthanides, establishing the main factors determining the effectiveness of 4f-luminescence of lanthanide ions at the molecular and nanoscale level Using various synthetic approaches heteronuclear lanthanide (Nd (III), Eu (III), Tb (III), Yb (III), Lu (III)) and p-metals (Al (III), Ga (III)) with aminopolycarboxylic and aminopolyphosphonic complexones were obtained. A modification of p-tert-butylcalix[4]arene with fragments of complexones was made, homonuclear lanthanide-containing complexes based on functionalized ligands were received. The methods for obtaining of nanosized silica particles containing homo-or heteronuclear complexes of lanthanides, attached to silica polymer matrix by both covalent and non-covalent interactions. Spectral-luminescent properties of homo- and heteronuclear lanthanide complexes were studied. It was found that p-metal acts as a kind of organizer of a rigid system, which leads to increased 4f-luminescent properties of coordination compounds. Photophysical properties of the systems were investigated and the main factors that determine the effectiveness of 4f-luminescence of lanthanide ions in the visible and near-infrared at the molecular and nanoscale level Product Description popup.authors Коровін Олександр Юрійович Смола Сергій Сергійович Снурнікова Ольга Віталіївна popup.nrat_date 2020-04-02 Close
