Description

The organic electroluminescence device of new organic electroluminescent compounds and this compound of use
Technical field
The organic electroluminescence device that the present invention relates to new organic electroluminescent compounds and use this compound more specifically, relates to as the new organic electroluminescent compounds of electroluminescent material and the organic electroluminescence device that uses this compound.
Technical background
In display device, electroluminescent (EL) device is favourable, because they provide contrast gradient and the quick speed of response of wide visual angle, excellence as the self-emission display device.Eastman Kodak Co (EastmanKodak) has at first developed a kind of organic EL device in 1987, this device uses low molecular weight aromatic diamines and aluminum complex as the material [Appl.Phys.Lett.51,913,1987] that forms electroluminescence layer.
Organic EL device is the device with following characteristic, and in the time of when electric charge is applied to the organic membrane that forms between electron injection electrode (negative electrode) and hole injecting electrode (anode) on, electronics and hole form pairing, then buries in oblivion also luminous.Can at the clear flexible base material, for example form this device on the plastics.Compare plasm display panel or inorganic EL indicating meter, described device can be worked under low voltage (being no more than 10V) and lower watt consumption condition, has simultaneously good purity of color.Because organic electroluminescent (EL) device can show three kinds of colors (green, blue and red), they have been considered to follow-on full-color display spare.
In organic EL device, determine that the greatest factor of its performance (comprising luminous efficiency and working life) is electroluminescent material.The ask for something of electroluminescent material comprises the anti-decomposability in high solid-state electroluminescent quantum yield, high electronics and hole mobility, the vacuum deposition process, ability and the stability of formation uniform thin film.
Usually, organic EL device generally has the structure of anode/hole injection layer (HIL)/hole transport layer (HTL)/emissive material layer (EML)/electron transport layer (ETL)/electron injecting layer (EIL)/negative electrode.Can be according to the organic electroluminescence device that how to form luminous material layer and form blue light-emitting, green glow or ruddiness.
In function aspects, described electroluminescent material can be divided into substrate material and dopant material.Usually, knownly provide excellent EL character by doping agent being doped to the electroluminescence layer that makes in the matrix.At present, develop the organic EL device with high-level efficiency and long service live and just becoming a urgent task.In particularly considering to the required EL performance level of large size oled panel, need in a hurry exploitation compare existing electroluminescent material excellence many materials.
Simultaneously, for conventional blue material, since the emerging product of bright dipping company (Idemitsu-Kosan) develops diphenylacetylene biphenyl (DPVBi) (compound a), developed many materials and realized commercialization.Except the blue material system of the emerging product of bright dipping company, known in addition dinaphthyl anthracene (DNA, compound b), four uncle Ding Ji perylene (compound c) systems etc.But, also tackle these materials and research and develop widely.
Distyryl based compound [distryl compound] system of the emerging product of bright dipping company is known to have the highest so far efficient, and power efficiency is 6lm/W, and the active parts life-span was greater than 30,000 hours.But when being applied to full-color display, owing to the prolongation of purity of color with the working hour descends, its life-span only has several thousand hours.In blue coloured electroluminous situation, if the electroluminescent wavelength moves to longer wavelength, it is favourable to become aspect luminous efficiency.But, this material is applied to high-quality indicating meter and is not easy, reason is blue purity of color and unsatisfactory.In addition, because the problem of purity of color, efficient and thermostability aspect, in the urgent need to this class material is researched and developed.
Figure BDA00002415256500021
Therefore, material commonly used does not form the thin film layer of matrix-doping agent, but forms individual layer.And, determine that from purity of color and efficient their commercial applications have difficulty.The authentic data that to also have a problem be the long lifetime aspect is not enough.
Similarly, for green fluorescent material, developed and be widely used following system: with coumarin derivatives (compound d, C545T), quinacridone derivative (Verbindung), DPT (compound f) mix as the Alq of matrix with percentum to tens as doping agent.The initial luminous efficiency performance level that these electroluminescent materials commonly used demonstrate can be used for commercialization.Yet, on the rapid decline of initial luminous efficiency and the working life problem is arranged also.Therefore, green fluorescent material has limitation, is difficult to adopt in the high-performance panel of giant-screen.
Figure BDA00002415256500031
In addition, because green fluorescent material does not have enough working lives for the OLED device, the more stable substrate material that needs exploitation to have high-performance.
Summary of the invention
Technical problem
Therefore, in order to address the above problem, the purpose of this invention is to provide the organic electroluminescent compounds that a kind of luminous efficiency and device service life as compared current material improve to some extent and have good skeleton (backbone) and suitable chromaticity coordinates.Another object of the present invention provides uses organic electroluminescent compounds as the organic electroluminescence device of electroluminescent material.
Technical scheme
One total aspect, the invention provides a kind of organic electroluminescent compounds that is represented by Chemical formula 1 and the organic electroluminescence device that uses this compound.Because organic electroluminescent compounds of the present invention has superior luminous efficiency and good life properties, it can be used for making the OLED device, and this device has very superior working life and because the watt consumption that improved power efficiency causes is low.
