Description
Technical field
The present invention relates to the novel anthracene derivative that contains triazine ring of a class, is that starting raw material makes by commercial 2-methylanthraquinone and fragrance group halohydrocarbon.Compound provided by the present invention is the blue organic electroluminescent material that a class has electronic transmission performance.
Background technology
Organic electroluminescent LED (OLED) has been subjected to the close attention of scientific and technological circle and industrial community because of its huge applications prospect in various indicating meters.Through the effort of two more than ten years, the part commercialization of present green device, and blue and red device or because of efficient or because of reasons such as life-spans still have distance from industrialization.Because the end-use of organic electroluminescence, be large-size ultra-thin colorful display screen of new generation (Science, 1996,273,884; Journal of the American Chemical Society, 2002,124,11576), therefore, study novel redness and blue emitting material and device, significant.
With regard to blue emitting material, that generally uses at present has an ADN, TBADN, and BCzVBi, DPVBi etc., these materials can adopt doping, also can directly use as the main body luminescent layer.Because evaporation thickness and doping is different, the device of acquisition can be launched light from dark blue to sapphire (Liao, C.-H.; Lee, M.-T.; Tsai, C.-H.; Chen, C.H, Applied Physics Letters, 2005,86 (20), 203507/1-203507/3).In addition, ADN, TBADN and BCzVBi have hole-transfer ability preferably, in making the device process, if film thickness monitoring is improper, light device after, the hole is delivered among the electron transfer layer AlQ easily, thereby obtains launching the device of bluish-green coloured light.So,, need control evaporation thickness and doping carefully, be unfavorable for mass-produced devices like this, particularly the occasion of having relatively high expectations in yield rate in order to guarantee to obtain pure blue-light-emitting.
Compound in triazine class has thermostability and electron transport ability preferably, in recent years, studies confirm that also it has hole barrier ability (C.J.Tonzola, M.M.Alam, W.Kaminsky, S.A.Jenekhe, J.Am.Chem.Soc.2003,125,13548).If triazine ring is introduced in the existing blue light material, by the effect of triazine ring, can adjust the bandwidth of existing blue light material, make its emission wavelength blue shift; Simultaneously, utilize the hole barrier ability of triazine ring, can prevent effectively that the hole from entering and cause the emission wavelength red shift among the AlQ; In addition, the electronic transmission performance of triazine ring can improve the transmission speed from the current carrier of negative electrode, thus the transmission speed in opposite directions of hole in the balancing device and electronics, and then the luminous efficiency of raising device.Based on this, it is starting raw material that the present invention adopts the cyano group anthracene, and by the cyclization of cyano group, a synthetic class contains the anthracene derivative of triazine ring, thereby obtains novel efficient blue light material with electron transport ability.
