13-pentacenequinone to access ethynylated pentacene ketones, namely, 13-hydroxy-13-(ethynylated)pentacene-6(13H)-ones. These pentacene ketones (“pentacenones”) serve as divergent intermediates to unsymmetrically 6,13-disubstituted pentacenes, commonly used for studying singlet fission processes and charge transport phenomena in organic field effect transistors. We report a synthetic method to access pentacenones
我们报告了 6,13-并五苯醌去对称化以获得乙炔化并五苯酮的一般方法,即 13-hydroxy-13-(ethynylated)pentacene-6(13 H)-那些。这些并五苯酮(“并五苯酮”)作为不对称 6,13-二取代并五苯的发散中间体,通常用于研究有机场效应晶体管中的单线态裂变过程和电荷传输现象。我们报告了一种获取并五苯酮的合成方法,该方法利用粗混合物的沉淀/结晶来实现多克规模的轻松纯化。并五苯酮的 X 射线晶体学分析揭示了有助于结晶的关键非共价相互作用,特别是酮和醇官能团之间的氢键以及 π-π 堆积和偶极-偶极相互作用。
