New highly fluorescent bifunctional anthracenes showed high thermal and electrochemical stability, and great potential as both blue emitters and hole-transporters for OLEDs. Deep-blue and Alq3-based green devices with maximum efficiencies and CIE coordinates of 1.65 and 6.25 cd A−1, and (0.15, 0.16) and (0.26, 0.49) were achieved, respectively.
Synthesis and characterization of 9,10-substituted anthracene derivatives as blue light-emitting and hole-transporting materials for electroluminescent devices
New 9,10-substituted anthracene derivatives were designed and synthesized for application as blue-emitting and hole-transporting materials in electroluminescent devices. They were characterized by H NMR, C NMR, FTIR, UV–vis, PL spectroscopy, and mass spectrometry. The theoretical calculation of three-dimensional structure and the energy densities of HOMO and LUMO states, as well as optical properties
设计并合成了新的9,10-取代的蒽衍生物,用作电致发光器件中的发蓝光和空穴传输材料。它们的特征在于1 H NMR,13 C NMR,FTIR,紫外可见光,PL光谱和质谱。三维结构的理论计算以及HOMO和LUMO态的能量密度以及这些新获得的材料的光学性质支持了它们具有非共面结构的说法。可以通过改变外围取代基来调节它们的光学,热和电化学性质。它们都是电化学和热稳定的分子。具有给电子三苯胺作为外围取代基的材料作为发蓝色光的材料和用于电致发光器件的空穴传输材料都显示出有希望的潜力。获得了具有最大亮度效率和CIE坐标分别为1.65 cd / A和(0.15,0.16)和6.25 cd / A和(0.26,0.49)的高效蓝色和基于Alq3的绿色OLED。
