Synthesis of Heterographenes via Tandem Hetero-Friedel-Crafts Reactions

近年来，我们开发了串联异质- friedel Crafts反应和多重交叉偶联反应合成杂石墨烯，引起了化学家和物理学家的广泛关注。利用这些反应，我们成功地短步合成了杂片烯、杂片烯的亚结构分子。这些分子表现出较高的电荷输运能力和荧光特性，从而使我们能够高效率地制备磷光OLED。杂环石墨烯是一种极具发展前景的新型有机电子材料。

We have developed tandem hetero-Friedel Crafts reactions and multiple cross-coupling reactions toward synthesis of heterographene, which attracts the interest of chemists and physicists in recent years. Using these reactions, we have succeeded in short-step synthesis of heteronanographenes, substructure molecules of heterographenes. These molecules showed high charge transport ability and fluorescence property and thus enabled us to fabricate phosphorescent OLED with high efficiency. Heteronanographenes are new and promising materials for organic electronics.
