Embodiment 1

[0031] 1. Synthesis of polystyrene ligands containing 8-hydroxyquinoline at the end

[0032] Add the initiator, monomer (styrene), catalyst and solvent into the polymerization tube, and remove the oxygen in the system by continuous vacuuming and nitrogen filling, then put the polymerization tube into the oil bath and react at 90-130°C 3-10 hours. The resulting polymer was precipitated in methanol and washed with 1:1 hydrochloric acid to remove the catalyst. The polystyrene ligand containing 8-hydroxyquinoline in the terminal group can be obtained by suction filtration and vacuum drying, and its molecular weight can be adjusted by controlling the ratio of the monomer and the initiator.

[0033] The initiator used in this embodiment is 5-chloromethyl-8-hydroxyquinoline; the catalyst can be the complex of cuprous chloride and pentamethyldiethylenetriamine or 2,2'-bipyridine; the solvent is cyclic Hexanone, anisole, N, N-diformamide, etc.

Abstract

The present invention discloses a kind of ternary high molecular europium complex comprising macro molecular ligand, beta-diketone compound and trivalent europium, and the macro molecular ligand is polyethylene with terminal radical containing 8-hydroxy quinoline unit. The preparation process includes: atom transferring free radical polymerization to synthesize polyethylene with terminal radical containing 8-hydroxy quinoline unit; synthesizing small molecular weight complex with trivalent europium and beta-diketone; and final coordinating exchange reaction to synthesize the high molecular complex of trivalent europium. The present invention is used as light converting agent with fluorescent emitting spectrum well fitting the absorption spectrum of chlorophyll, and the obtained high molecular complex of trivalent europium is well compatible with polyethylene matrix, so that the present invention is especially suitable for use in preparing farm light converting film with high efficiency.

Description

technical field [0001] The invention relates to a polymer rare earth complex and its preparation process, especially a polymer-trivalent europium ternary complex and its preparation process, as well as its application in the preparation of light conversion films. Background technique [0002] The growth of plants depends on the absorption and utilization of sunlight by photosynthesis, but not all parts of sunlight can be absorbed and utilized by plants. Plant chlorophyll mainly absorbs blue-green light (400-500nm) and red-orange light (625-700nm) in sunlight during photosynthesis. The ultraviolet part of sunlight not only cannot be absorbed and utilized by plants, but also harmful to the growth of plants. More importantly, ultraviolet light in sunlight has a strong degradation effect on agricultural films, seriously affecting the service life of agricultural films. The function of light conversion film is to convert ultraviolet light in sunlight in...
