Abstract

The invention discloses a kind of luminous organic material and its organic luminescent device, is related to organic optoelectronic materials technology.The present invention is by introducing class anthracene class rigid structure, show good heat endurance, and its diffraction is prepared into device, especially as the material of main part in organic electroluminescence device, possesses the features such as low driving voltage, high brightness, outstanding heat resistance and high efficiency, better than existing conventional OLED.

Description

A kind of luminous organic material and its organic luminescent device
Technical field
The present invention relates to organic photoelectrical material technical field, more particularly to a kind of luminous organic material and its organic illuminator Part.
Background technology
Organic electroluminescent LED (Organic Light Emitting Diode, OLED) has pure flat display (Cathode Ray Tube, CRT) and the overall merit of liquid crystal display (Liquid Crystal Display, LCD), is described as The FPD of 21 century and third generation Display Technique, it has also become a current international big study hotspot.
In general organic luminescent device (OLED) is the organic matter layer structure by being inserted between negative electrode, anode and negative electrode and anode Into, the composition of device is transparent ITO anode, hole injection layer (TIL), hole transmission layer (HTL), luminescent layer (EL), hole The negative electrodes such as barrier layer (HBL), electron transfer layer (ETL), electron injecting layer (EIL), LiAl are formed, and can omit 1~2 on demand has Machine layer.Voltage is formed between two electrodes of device, while being injected from cathode electronics, another side anode injection hole.Electronics and Hole returns to stable ground state and generates light transmitting in luminescent layer in conjunction with excitation state, excitation state is formed.Luminescent material is divided into glimmering Luminescent material and phosphor material, the forming method of luminescent layer are the methods that phosphor material (organic metal) is adulterated in fluorescent host material With the method for fluorescent host material doping fluorescent (organic matter for including nitrogen) dopant.It is to have to generally form emitting layer material The parts such as centerbody and benzene, biphenyl, naphthalene, heterocycle such as benzene, naphthalene, fluorenes, the fluorenes of spiral shell two, anthracene, miscellaneous anthracene pyrene, carbazole；Contraposition, meta, ortho position Binding site and the replacing structure such as cyano group, fluorine, methyl, the tert-butyl group.
At present, the research of electroluminescent organic material is carried out extensively in academia and industrial quarters, a large amount of function admirables Electroluminescent organic material be developed successively, but the technological industrialization process still faces many key issues how Design the more preferable material of new performance to be adjusted, be always those skilled in the art's urgent problem to be solved.
The content of the invention
It is an object of the invention to provide a kind of luminous organic material and its organic luminescent device.Organic hair provided by the invention Luminescent material thermal stability is high, preparation method is simple, is used and manufactured using the compound as the material of main part in luminescent layer Organic luminescent device, the advantages of driving voltage is low, luminous efficiency is high is shown, be the luminous organic material of function admirable.
