Extensive intramolecular π-conjugation is considered to be requisite in the design of organic semiconductors. Here, two inkjet pigments, epindolidione and quinacridone, that break this design rule are explored. These molecules afford intermolecular π-stacking reinforced by hydrogen-bonding bridges. Air-stable organic field effect transistors are reported that support mobilities up to 1.5 cm(2)/Vs with T80 lifetimes comparable with the most stable reported organic semiconducting materials.
广泛的分子内π共轭被认为是有机半导体设计的必要条件。在这里，我们探索了两种喷墨颜料，即呫吨酮和喹吖啶酮，它们打破了这一设计规则。这些分子提供了由氢键桥增强的分子间π堆积。报道了空气稳定的有机场效应晶体管，其迁移率高达 1.5 cm²/Vs，T80 寿命与报道的最稳定的有机半导体材料相当。
