The synthesis of soluble dibenzobarrelene-substituted azaacenes either by condensation reactions in solution or, more effectively, in the solid state by using a ball mill is reported herein. We relate their optical properties in thin films to their packing in the solid state. The targets are characterized by cyclic voltammetry, X-ray crystallography and UV/Vis and fluorescence analysis. Three highly fluorescent, amorphous azaacenes were processed into organic light-emitting diodes, and their improved performance (luminance, efficiency and efficacy) was compared with that of structurally related iptycene-based azaacenes.
本文报道了通过溶液中的缩合反应，或者更有效地通过使用球磨机在固态下合成可溶性二苯并桶烯取代的氮杂并苯。我们将它们在薄膜中的光学性质与其在固态下的堆积情况联系起来。通过循环伏安法、X射线晶体学以及紫外/可见和荧光分析对目标产物进行了表征。三种高荧光性的非晶态氮杂并苯被加工成有机发光二极管，并将其改善后的性能（亮度、效率和功效）与结构相关的基于异丙苯的氮杂并苯的性能进行了比较。
