Purpose - Optimization of methods for the synthesis of organic- inorganic nanocomposite materials containing lanthanide complexes with beta- diketones , aminopolycarboxylic polydentate acids, modified calix[4]arenes and porphyrins in silica media and research and comparison of their spectral-luminescent properties for further practical tests; identifying opportunities for conjugation of lanthanide-containing nanocomposite materials for polymer matrices of different chemical nature in order to increase photoluminescent characteristics Optimization of methods for the synthesis of silicate nanocomposites containing complexes of Nd (III), Eu (III), Er (III), Yb (III) and Lu (III) with beta- diketones , and nitrogen-containing complexones, carboxyl or aminoderivatives tetraphenilporfirynes or calix[4]arenes was made. Conditions of conjugation of lanthanide-containing nanocomposite materials for polymer matrices were determined. The structure of the polymer nanocomposite systems as well as comparison of photophysical characteristics of the compounds obtained with previous silica materials was established. A comparative analysis of the characteristics of materials of different nature ( polymers silica compounds and hybrid materials) was made to determine the most promising systems for further practical test. The most promising sites for further practical tests were chosen Product Description popup.authors Коровін Олександр Юрійович Русакова Наталя Володимирівна Семенішин Микола Миколайович Смола Сергій Сергійович Снурнікова Ольга Віталіївна Фадєєв Євген Миколайович popup.nrat_date 2020-04-02 Close
