多芳胺取代均三嗪的合成及其光电性能的研究

设计合成了一个新的带有三支链的均三嗪衍生物分子: 2,4,6-三4-(N,N-二对甲苯基)-苯胺乙基]均三嗪(TBTN); 用1H NMR, 13C NMR, IR, MS (MALDI-TOF)和元素分析确认了化合物的结构. 研究了该化合物的紫外吸收光谱、荧光光谱、电致发光光谱等性能, 用TBTN组装发光器件, 实验结果显示TBTN为发光层时, 该器件能发出稳定白光. 器件结构为ITO/2-TNATA (30 nm)/NPB (20 nm)/TBTN (30 nm)/Alq3 (30 nm)/LiF (0.5 nm)/Al, 在电压为15 V获得最大亮度是1523 cd/m2, 在驱动电压范围内CIE(国际照明委员会)坐标稳定并在白色等能区内.

Polyarylamine Substituted Triazine and Its Performance of Photo-electricity

A novel emitting material with a branched molecular structure 2,4,6-tris{4-N,N-di(p-tolyl)- amino]styryl}-1,3,5-s-triazine (TBTN) has been synthesized, which was confirmed by 1H NMR, 13C NMR, IR, MS (MALDI-TOF), elemental analysis and characterized by UV-visible, photoluminescence (PL) and electroluminescence (EL) spectroscopy. A bright and color stable white was obtained from the organic light- emitting diodes (OLED) of ITO/2-TNATA (30 nm)/NPB (20 nm)/TBTN (30 nm)/Alq3 (30 nm)/LiF (0.5 nm)/Al, in which TBTN was used as an emitting layer. The maximum brightness of 1523 cd/m2 coming from the white organic light-emitting device (WOLED) was measured at the driving voltage of 15 V, more-over, the CIE (International Commission on Illumination) coordinate of the white-emitting device was stable on bias voltage.
