Abstract: Cross-linked polymer particles containing centers of molecular recognition of toluene and prepared in the presence of luminophoric bromine-containing or hydroxyl-containing derivatives of 1,3-diphenyl-β-diketonate boron difluoride using styrene, methacrylic acid, ethylene glycol dimethacrylate and divinylbenzene are obtained for the first time. The influence of cross-linked particle characteristics (core particle diameter, core / shell particle diameter, shell thickness, particle size distribution) on the luminescent properties of their films is shown. The stability of bromine-containing or hydroxyl-containing derivatives of β-diketonate boron difluoride in different solvents (deuterotoluene, deuterochloroform) as well as at a temperature of 60 ℃ and in the presence of the initiator, α,α'-azoisobutyronitrile, that models the conditions of cross-linked polymer particle synthesis, is studied by 1H, 11B and 13C NMR spectroscopy. Furthermore, the sorption of ethanol by 3D-ordered structures based on the particles obtained is investigated by means of NMR spectroscopy and the changes of the luminescence spectra of such structures in the presence of toluene vapors are studied
