摘要
FIELD: chemistry.;SUBSTANCE: invention relates to novel complexes of rare-earth elements, which can be used as active layers of organic light-emitting diodes, optical-electronic devices as well as fluorescent labels and markers. Disclosed is a luminescent anionic complex of rare-earth elements of formula [Ln(L1)4]-M+ (I), where Ln is an ion of a trivalent rare-earth element; L1 is a diketonate ligand - a derivative of 3-polyfluoroalkyl-1-pyrazolyl-1,3-propanedione of formula (II), where Rf is CH2F, CHF2, CF3, fluorinated alkyl, cycloalkyl or aryl; M+ is a univalent cation of an alkali metal or an ammonium ion, a residue of a quaternary ammonium base, a cation of pyridinium or a secondary amine or a tertiary amine. A method of producing compound (I) is also disclosed.;EFFECT: invention enables to obtain novel compounds (I) with high luminescence intensity compared to their non-fluorinated counterparts, and also enables to vary in a wide range such process parameters of compounds (I) as thermal stability, film-forming capacity, solubility and volatility in a vacuum, which are necessary for use in optical-electronic devices.;2 cl, 3 dwg, 8 ex
