LANTHANIDE COMPLEXES EXHIBITING LUMINESCENT PROPERTIES, METHOD OF DETERMINING GLUCOSE CONCENTRATION BASED ON THEM Russian patent published in 2024 - IPC C07F5/00 C07F5/02 G01N21/64 G01N33/487 C09K11/06 C07C63/00 C07D221/06 

FIELD: chemistry.

SUBSTANCE: group of inventions can be used to determine the concentration of glucose in aqueous solutions using phosphors. Complexes of lanthanide carboxylates with the general formula Ln(L)₃(Phen)_n(H₂O)_х, exhibiting luminescent properties, have been proposed, where Ln = Gd, Eu_mTb_1-m, at m = 0…1, L^- = C₆B(OH)₂R¹R²R³R⁴COO^-, n = 0, x = 1-4 or n = 1, x = 0-4. Each of R¹, R², R³, R⁴ – H or halogen, or aryl, or fluorophenyl, or B(OH)_2, or alkyl, Phen is o-phenanthroline. The following is also proposed: a method of determining the concentration of glucose in an aqueous solution using complexes of lanthanide carboxylates.

EFFECT: group of inventions makes it possible to expand the arsenal of luminescent lanthanide complexes and methods of determining glucose concentration.
