FIELD: chemistry.
SUBSTANCE: present invention relates to methods of producing fluorescent high-molecular weight compounds. Described is a method of producing a fluorescent polymer through polymerisation of a vinyl monomer in an organic solvent to form flexible polymer chains between fluorescent blocks using a fluorescent macroinitiator, in the presence of a catalyst based on a transition metal complex and an optional ligand, characterised by that said polymerisation takes place in a single step in an ether solvent based on participation therein of a fluorescent macroinitiator, which is formed during polymerisation as a result of using an initiator - p-dihalobenzene or 2,7-dihalofluorene, which contain halogens: iodine, bromine, chlorine or combination thereof, and use of said catalyst in form of a nickel complex with phosphine ligands: bis-triphenylphosphine nickel dibromide or bis-triphenylphosphine nickel dichloride combined with an activator-reducing agent - zinc dust. Described also is a method of producing a fluorescent polymer through polymerisation of a vinyl monomer in an organic solvent to form flexible polymer chains between fluorescent blocks using a fluorescent macroinitiator, in the presence of a catalyst based on a transition metal complex and an optional ligand, characterised by that said polymerisation is carried out in two steps, comprising a first step for: preliminary synthesis of a fluorescent macroinitiator by reacting p-dihalobenzene or 2,7-dihalofluorene, which contain halogens: iodine, bromine, chlorine or combination thereof, in an ether solvent in the presence of a catalyst - nickel complex with phosphine ligands: bis-triphenylphosphine nickel dibromide or bis-triphenylphosphine nickel dichloride combined with an activator-reducing agent - zinc dust, and a second step for: polymerisation of a vinyl monomer in an ether solvent in the presence of the fluorescent macroinitiator catalyst - nickel complex with phosphine ligands: bis-triphenylphosphine nickel dibromide or bis-triphenylphosphine nickel dichloride combined with an activator-reducing agent - zinc dust, obtained at the first step.
EFFECT: high technological effectiveness of producing a fluorescent polymer.
