We report the synthesis of processible (dihydro)pyracyclene‐ and acenaphthylene‐substituted azaacenes using condensation reactions in solution. The targets are characterized via cyclic voltammetry, X‐ray crystallography, UV/Vis, fluorescence spectroscopy and DFT/NICS calculations. Formal hydrogenation of the annulated five‐membered ring surprisingly alters emission in the solid‐state as a consequence
我们报告了使用溶液中的缩合反应合成可加工的(二氢)
吡咯环烯和取代的氮杂并氮杂
环丁烷。通过循环伏安法,X射线晶体学,UV / Vis,荧光光谱和DFT / NICS计算来表征目标。由于芳香性和HOMO-LUMO重叠的调节,环状五元环的正式加氢惊人地改变了固态的发射。在有机发光二极管中,研究了五种高度荧光的结晶氮杂
蒽,将其作为发光体,并将它们在亮度和效率方面的性能与结构相关的氮杂丁的性能进行了比较。
