Description
Technical field
The invention belongs to the organic electronic transmission/hole barrier materials field in the organic electroluminescence device, be particularly related to a class polyaryl substituted pyridine derivative and a synthetic method thereof that is used for organic electronic transmission and/or hole barrier materials, and with the purposes of such polyaryl substituted pyridine derivative material preparation organic electroluminescence device aspect.
Along with the arriving of Development of Multimedia Technology and information society, more and more higher to the flat-panel monitor performance demands.In recent years emerging three kinds of technique of display: plasma display, Field Emission Display and display of organic electroluminescence (OLED) have all remedied the deficiency of cathode ray tube (CRT) and liquid-crystal display (LCD) to a certain extent.Wherein, a series of advantages such as OLED has from main light emission, low voltage direct drive, solidifies entirely, the visual angle is wide, color is abundant, compare with liquid-crystal display, OLED does not need backlight, the visual angle is big, low in energy consumption, its response speed reaches 1000 times of liquid-crystal display, its manufacturing cost but is lower than the liquid-crystal display of equal resolving power, therefore, organic electroluminescent LED (OLEDs) is owing to its potential application in indicating meter of new generation and lighting engineering causes extensive attention, and its application prospect is very wide.Organic electroluminescence device is spontaneous luminescent device, and the luminous mechanism of OLED is under the extra electric field effect, and electronics and hole are injected the back from positive and negative polarities respectively and produced luminous in organic materials migration, compound and decay.The typical structure of OLED comprises cathode layer, anode layer, and the organic thin film layer between this is two-layer, can comprise one or more functional layers in electron injecting layer, electron transfer layer, hole blocking layer, hole transmission layer, hole injection layer and the organic luminous layer in the organic thin film layer.Since the C.W.Tang of Eastman Kodak Company (C.W.Tang and S.A.Vans lyke, Applied Physics Letters, Volume 51, P913,1987) reported since the laminated type organic electroluminescent device of low voltage drive, people have carried out a lot of researchs (U.S.Pat.Nos.5,141,671 to utilizing organic materials as the organic electroluminescence device of composition material; 4,539,507; 6,020,078; 5,935,720; 5,972,247; 5,593,788; 4,885,211; 5,059,862; 5,104,740; 5,069,975; 5,126,214; 5,389,444; 6,165,383; 6,245,449; 6,861,162B2; 6,833,202B2; Chen, Shi and Tang, Macromol.Symp., 1997,125,1; Segura, Acta.Polym., 1998,49,319; Mitschke and Bauerle, J.Mater.Chem.2000,10,1471).Yet, although have
Pyridine ring is because its electron deficiency characteristic has certain electronegativity, and its reduction potential is about 2.6eV (vsSCE).Its polymkeric substance, at 2.9～3.5eV, and therefore Ip can be used as the electron transport material in the polymer electroluminescent device at 5.7～6.3eV as the EA value of polypyridine.Yet,, its luminosity is changed because its strong intramolecular interaction (overlapping as ∏-∏) easily forms exciplex in film.Therefore, device performance is not good enough.So far seldom in organic electroluminescence device, use.
Summary of the invention
The objective of the invention is to overcome the problem that exists in the above-mentioned organic electronic transmission/hole barrier materials, the organic electronic transmission and/or the hole barrier materials of a class polyaryl substituted pyridine derivative is provided; By molecular designing, introduce some large-substituents and make it be difficult for forming exciplex, and suppress its crystallisation process with rigid structure, improve its film-forming properties, improve its charge transport properties; Simultaneously, the destruction of molecule coplanarity will make its emission peak blue shift, and then reach the purpose of improving device performance.
A further object of the present invention provides the organic electronic transmission of purpose one and/or the synthetic method of hole barrier materials.
Organic electronic transmission and/or hole barrier materials that an also purpose of the present invention provides purpose one are used to prepare organic electroluminescence device, especially the purposes of blue organic electroluminescence device aspect.
The present invention relates to the organic electronic transmission and/or the hole barrier materials of the polyaryl substituted pyridine derivative of a class tool electrophilic character, this compounds has very high electron affinity (about 3.5eV) and ionization potential (about 7.0eV), can be used for the electron transport material and/or the hole barrier materials of organic electroluminescence device.The molecular structure of material of the present invention is shown in following general formula.With the prepared organic electroluminescence device of material of the present invention because and have only very little barrier potential (about 0.2eV) between the negative electrode, electronic energy is injected in the organic luminous layer effectively, so its device has a very low bright voltage (2.7eV), simultaneously because high ionization potential (about 7.0eV) is arranged, blocking hole is diffused into negative electrode effectively, thereby the limit that reaches hole and electronics obtains effect.Material of the present invention has very high photoluminescence efficiency (about 100%) and ultraviolet region emission wavelength (370nm), there is not the quencher phenomenon that causes because of energy transformation, can be used for making all organic electroluminescence devices, blue-light device particularly, thus the performance of corresponding electron luminescence device improved effectively.Material of the present invention has high glass-transition temperature and high thermal stability simultaneously, so the life-span of electroluminescent device is effectively improved.
The present invention adopts easy method to synthesize a series of class polyaryl substituted pyridine derivatives with efficent electronic transmission and/or hole barrier materials.Organic electroluminescence device of the present invention comprises negative electrode, anode and organic thin film layer, at least comprise organic luminous layer in the organic thin film layer between negative electrode and anode, and in the organic thin film layer at least one deck comprise following general formula (I), (II) or (III) the polyaryl substituted pyridine derivative of expression.The polyaryl substituted pyridine derivative that preferred organic thin film layer comprises general formula (I), (II) or (III) represents.The molecular structure of a class polyaryl substituted pyridine derivative of the present invention is as follows:
