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 complex of rare-earth elements of formula [Ln(L1)3L2] (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-propanediol of formula 
(II), where RF is CH2F, CHF2, CF3, fluorinated alkyl, cycloalkyl or aryl, L2 is an auxiliary bidentate N, P or O-containing ligand. 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.
