Claim OLED).That be described as having fantasy display feature and FPD (flat panel display, FPD) technology-organic
Light emitting diode and display device thereof have received people and greatly pay close attention to.During electroluminescent, after electronics and hole-recombination,
Create singlet state and triplet exciton simultaneously, be 1 according to the ratio of the exciton number of spin statistics principle, singlet state and triplet
: 3, owing to the radiation transistion of triplet exciton is prohibited, the triplet exciton luminous efficiency of major part organic material is the lowest, and
The efficiency of organic electroluminescence device cannot be more than 25%.Atom centered by d10 element, its complex formed can occur
Multiple electron transition mode, is therefore effectively utilized triplet energies, improves its efficiency, it is achieved close to the 100% of theoretical value.
OLED phosphor material the most on sale is all the complex of precious metal iridium and platinum etc., although they in performance
Having preferably performance, but these transition metal are expensive, content is low, exploitation difficulty, limits them in reality in certain limit
Large-scale application in border life, production.Therefore, novel cheap metal complex photoelectric functional material is found the most aobvious
Obtain extremely important.For noble metal, copper has inexpensively, environmental protection, the advantage such as nontoxic, and China's copper resource reserve is rich
Richness, occupies third place in the world.Therefore, research based on univalent copper complex luminescence new material, there is very important theory significance
And actual application value.With Cu (I) complex as phosphor material the most long-standing (N.Armaroli, G.Accorsi,
F.Cardinali, A.Listorti, Top.Curr.Chem.2007,280,69-115.), this cheap Cu (I) complex
Luminescent material can be prepared easily by Cu (I) ion and suitable organic ligand.Cu (I) complex has abundant chemistry knot
Structure, has Cu (I) complex of monokaryon and double-core or even multinuclear, and its part is the most rich and varied, can be rigidity or flexibility, monodentate, double
Tooth or multiple tooth.Its coordination mode is changeable, and ligancy is multiple, at different conditions the cuprous cooperation of available different coordination mode
Thing, character also differs widely, and the research for luminescent material provides more possibility.The most at present at OLED operating temperature model
The luminous intensity enclosing Cu (I) complex phosphorescence material does not still reach application demand.Therefore novel cheap Cu (I) complex is developed
Phosphor material has great actual application value.

Son, cation is then to be complexed, by cuprous ion and part 2-iQBO, POP, the coordination cation formed；This complex cation
Middle cuprous ion uses CuN2P2Tetrahedral coordination mode, two of which N is respectively from a double-tooth chelate ligand 2-iQBO
In isoquinolin group and benzoxazoles group, two P come from another double-tooth chelate ligand POP；Its molecular structure such as formula
(II):
。
The preparation method of the most cuprous complex red phosphor material, its method comprises the following steps:
(1) by Cu (CH under room temperature3CN)4PF6Powder is dissolved in dichloromethane, obtains settled solution A；
(2) under room temperature, the powder of part POP is dissolved completely in dichloromethane, obtains settled solution B；
(3) under room temperature, the powder of part 2-iQBO is dissolved completely in dichloromethane, obtains settled solution C；
(4) stir after solution A, solution B and solution C being mixed, be allowed to fully occur complexation reaction；
(5), after adding isopropanol in reaction gained solution, steam to dry at normal temperature decompression backspin, obtain red crystals product.
The preparation method of the most cuprous complex red phosphor material, it is characterised in that: described three kinds
Mol ratio Cu (the CH of reactant3CN)4PF6: POP: 2-iQBO is 1: 1: 1.
The application of the most cuprous complex red phosphor material, it is characterised in that described luminescent material exists
There is maximum emission peak at 675nm, as red emission embedded photoluminescent material, or the luminescence in multilayer electroluminescent device can be used as
Layer luminescent material.
