For the first time, a direct single-step one-pot route to access nine new symmetric tetraalkynylated anthracenes via Pd(CH3CN)2Cl2/cataCXium®A catalyzed tetra-fold Sonogashira coupling is reported. Five of these tetraalkynylated anthracenes have been crystallographically characterized, with two of them exhibiting multiple interactions that significantly shorten the inter-planar distances in the solid-state
首次通过Pd(CH 3 CN) 2 Cl 2获得九种新型对称四炔化
蒽的直接单步法报道了 /cataCXium®A 催化的四重 Sonogashira 偶联。这些四炔基
蒽中的五种已被晶体学表征,其中两种表现出多重相互作用,显着缩短了固态结构中的面间距。这些分子表现出的丰富的光物理特性为未来在传感器和光电设备中的应用提供了巨大的希望。包含 D-π-A-π-D 基序的两种被考虑的四炔化
蒽表现出溶剂化变色和卤致变色,其中一个显示出 1.79 eV 的低带隙。其余化合物的带隙范围为 1.79–2.04 eV。
