A new kind of perylene-based 2D covalent organic framework (COF) is designed and synthesized based on the C2 + C2 topological diagram. The perylene-based COF is constructed via the condensation reaction using 2,5,8,11-tetrakis((4-formylphenyl) perylene (TFPPer) and 2,5,8,11-tetrakis(4-aminophenyl) perylene (TAPPer) as building blocks. The resulting TFPPer-TAPPer-COF features high crystallinity, excellent stability, intrinsic porosity, and an electron-rich skeleton. Significantly, the electrical performance of the COF can be enhanced through the encapsulation of fullerene (C60) into the 1D channels via donor–acceptor interaction. Compared to the pristine COF, the electrical conductivity of C60@TFPPer-TAPPer-COF can be greatly increased from 8.98 × 10−8 to 1.59 × 10−5 S cm−1, meanwhile the carrier mobility rises from 1.04 × 10−3 to 4.23 × 10−2 cm2 V−1 s−1. The improvement in electrical performance stems from the strong donor–acceptor interaction between perylene and C60. These results provide insights into the rational construction of conductive COFs through donor–acceptor interaction and demonstrate their great potential in related application fields.

通过供体-受体相互作用包封富勒烯合理构建导电共价有机骨架
基于C 2 + C 2拓扑图，设计合成了一种新型苝基二维共价有机骨架（COF） 。基于苝的 COF 是通过使用 2,5,8,11-四((4-甲酰基苯基)苝 (TFPPer) 和 2,5,8,11-四(4-氨基苯基)苝 (TAPPer) 的缩合反应构建的作为构建块。由此产生的 TFPPer-TAPPer-COF 具有高结晶度、优异的稳定性、固有孔隙率和富电子骨架。重要的是，COF 的电性能可以通过将富勒烯 (C 60 )封装到通过供体-受体相互作用形成一维通道。与原始 COF 相比，C 60的电导率@TFPPer-TAPPer-COF 可以从8.98 × 10 -8大幅增加到1.59 × 10 -5 S cm -1，同时载流子迁移率从1.04 × 10 -3增加到4.23 × 10 -2 cm 2 V -1 s -1。电性能的改善源于苝和 C 60之间强烈的供体-受体相互作用。这些结果为通过供体-受体相互作用合理构建导电 COF 提供了见解，并展示了它们在相关应用领域的巨大潜力。
