SYNTHESIS AND STUDY OF THE LUMINESCENT PROPERTIES OF WATER-SOLUBLE C-DOTS

Carbon dots are a promising area in the field of luminescent materials. We obtained yellow and blue C-dots through hydrothermal synthesis followed by centrifugation, filtration and dialysis. The synthesized carbon dots can be used in the production of optical materials, biomedicine and theranostics.Исследование выполнено за счет гранта Российского научного фонда (проект №20-73-10091)

Effective Light Converters Based on Mesogenic B-Diketonate Complexes of Europium

A Eu3+ mesogenic complex was obtained and demonstrated the possibility of its application as a efficient light converter. It was shown that it is possible to obtain photo- and thermally stable film light converters that effectively absorb in the visible region λ=395-405 nm.Работа выполнена при финансовой поддержке гранта РНФ 18-13-00112

Magnetic investigations on liquid crystalline metallopolymers

Artículo de publicación ISIIn this contribution, magnetic investigations on materials, which essentially combine mesogenic and polymeric properties, were presented. In the glassy and the smectic phase of a copper(II) containing polymer we observed remarkable antiferromagnetic exchange interactions between the copper centers, whereas in the isotropic phase, the magnetism followed the Curie-Weiss law. The monomeric model compound showed Curie-Weiss behaviour. In addition, we describe the magnetic behaviour of mesogenic compounds, resulting from the incorporation of rare-earth ions in chelating units of the liquid-crystalline Schiff base polymer
