Description
Technical field
The present invention relates to coordination metal compound, luminescent coating formation material, organic electroluminescent device material and organic electroluminescent device, the stable high organic EL under particularly luminous efficiency height, high temperature are preserved; And can realize above-mentioned target, to the solvability excellence of organic solvent, not only by vacuum evaporation, also can be ready for use on the coordination metal compound of organic electroluminescent device by easy wet type film forming legal system; Organic electroluminescent device forms with material and luminescent coating and uses material.
Background technology
Organic electroluminescent device (following abbreviate electroluminescent as EL) is by applying electric field, utilizing by anode injected holes and the self-emission device that is made the luminous principle of fluorescent substance by the recombination energy of negative electrode injected electrons.Since the people such as C.W.Tang of イ one ス ト マ Application コ ダ ッ Network company have reported the low voltage drive organic EL that is obtained by the cascade type element (C.W.Tang, S.A.Vanslyke, Applied Physics Letters, 51 volumes, 913 pages, 1987 etc.) since, about in the ascendant as the research of the organic EL of constituent material with organic materials.People such as Tang are luminescent layer with three (oxine) aluminium, and the triphenyldiamine derivative is used for hole transmission layer.The advantage of stepped construction has: can improve the injection efficiency of hole to luminescent layer; Stop by the negative electrode injected electrons, improve the formation efficiency of the exciton of compound generation; The exciton that will generate in luminescent layer is closed etc.Shown in this example, the component structure of known organic EL has: 2 stratotypes of hole transport (injection) layer, electric transmission luminescent layer; Perhaps 3 stratotypes of hole transport (injection) layer, luminescent layer, electric transmission (injection) layer etc.In such cascade type structural element,, improve component structure or formation method etc. in order to improve the composite efficiency of injected holes and electronics.
Luminescent material as organic EL, known have luminescent materials such as chelating complex compound, coumarin derivatives, tetraphenylbutadiene derivative, bisstyryl arylene derivatives, oxadiazole derivative such as three (oxine) aluminium complex, have and report: can obtain the luminous of the extremely red visible region of blueness by them, be expected to realize color display element (for example with reference to Japanese kokai publication hei 8-239655 communique, Japanese kokai publication hei 7-138561 communique, Japanese kokai publication hei 3-200289 communique etc.).
In recent years, someone proposes in the luminescent layer of organic EL to utilize organic phosphorescent material except that luminescent material (for example with reference to " Improved energy transferin electrophosphorescent devices " Applied Physics letters Vol. 74 No.3 such as D.F.O ' Brien and M.A.Baldo, 442~444 pages, January 18,1999, M.A. " Very high-efficiencygreen organiclight-emitting devices based on electrophosphorescene " Applied Physics letters Vol. 75 No.1 such as Baldo, 4~6 pages, July 5,1999).
Like this, in the luminescent layer of organic EL, singlet state and triplet state by utilizing organic phosphorescent material excited state can realize high luminous efficiency.In the organic EL, when electronics and hole-recombination, because of the difference of rotation multiplicity, singlet state exciton and triplet exciton generate with 1: 3 ratio, therefore can think if use the phosphorescent luminescent material, can realize only using 3~4 times luminous efficiency of the element of fluorescence.
In the above-mentioned organic EL, for the excited state that do not make triplet state or the exciton delustring of triplet state, adopted following stacked formation: be followed successively by anode, hole transmission layer, organic luminous layer, electron transfer layer (hole blocking layer), electron injecting layer, negative electrode, used the luminiferous compound of matrix compounds and phosphorescence (for example with reference to No. 609714 specification sheets of United States Patent (USP), international publication WO01/41512 communique) in the organic luminous layer.In these patent documentations, matrix compounds has used 4,4-N, N-two carbazole biphenyl, but the second-order transition temperature of this compound is 110 ℃ or following, and symmetry is very good, therefore crystallization easily when carrying out the oven test of element in addition, has the problem of short circuit or generation picture element flaw.
In addition, when carrying out evaporation, have the generation crystal growths such as position of impurity or electrode protrusion, the A-stage before oven test can find to have produced defective.Have three symmetric carbazole derivative and also can be used as the matrix use.But, because symmetry is good, crystal growth takes place at the position that has impurity or electrode protrusion etc. during evaporation, this unavoidablely the A-stage before the oven test promptly produce defective.
Phosphorescence luminous thing uses iridium complex usually, luminescent layer by in the matrix compounds in certain proportion (number quality % or following) material of being mixed with iridium complex form.Usually, with respect to matrix compounds, the concentration of phosphorescence luminance compound is high more, and then luminous intensity is high more, but when reaching several %~tens of % left and right sides, this proportionlity imbalance, luminous intensity reduces, and the luminous efficiency of element is also low.Known this is concentration quenching or concentration inactivation, in Japanese kokai publication hei 05-078655 communique or Japanese kokai publication hei 05-320633 communique announcement arranged.This can think with the luminescence center material between or the radiationless transition that causes of the multimerization of luminescence center material and its periphery material reaction relevant.Therefore,, can not use the phosphorescence luminance compound in a large number, and must make its concentration reach best in order to realize high-level efficiency.
In recent years, the improvement research of phosphorescence luminance compound makes progress, the material that the element of easy film by wet makes has appearred being suitable for (for example with reference to Shao-An Chen etc., " High-Efficiency Red-Light Emission from PolyfuluorenesGrafted with Cycolometalated Iridium Complexes and ChargeTransport Moiety ", J.Am.Chem.Soc., Vol.125,636~637 pages, 2003 and the open communique US2003/0091862A1 of the U.S.).But present material luminous efficiency is low, and element stable low under the high temperature, lacks practicality.
Summary of the invention
The present invention establishes for solving above-mentioned problem, its purpose is to provide luminous efficiency height, high temperature to preserve the high organic EL of stability down, and the coordination metal compound to the solvability excellence of organic solvent, organic EL that can realize above-mentioned purpose are with material, luminescent coating formation material.
