We report herein the incorporation of xanthenyl units into two extended π‐conjugated phenylene systems, namely indenofluorene and pentaphenylene. Thus, dispiroxanthene‐indenofluorene (DSX‐IF) and dispiroxanthene‐ladderpentaphenylene (DSX‐LPP) have been designed and synthesized through short and efficient synthetic approaches. These two molecules possess a 3π‐2‐spiro architecture (3π‐systems/2‐spiro
我们在此报告将黄嘌呤单元并入两个扩展的π-共轭亚苯基系统,即茚并芴和五亚苯基。因此,通过短而有效的合成方法设计并合成了双螺并蒽蒽-茚并芴(DSX-IF)和双螺并蒽蒽-ladderpentaphenylene(DSX-LPP)。这两个分子具有3π‐2‐spiro结构(3π‐systems / 2‐spiro桥),其中两个黄嘌呤核与π共轭骨架螺线连接,DSX‐IF用于茚芴,DSX‐LPP用于五苯撑。已对这些蓝/紫光发射器的结构,电化学和光物理性质进行了详细研究,并将其与带有螺芴基核心而不是螺氧杂蒽基核心的“所有碳”类似物进行了比较,以前在文献中报道过的,即双螺芴-茚芴(DSF-IF)和双螺芴-ladderpentaphenylene(DSF-LPP)。最后,报道了DSX-IF和DSX-LPP在非掺杂有机发光二极管中作为新型发光材料的应用。值得注意的是,对不同的电致发光光谱进行了详细的光学研
