Web导语 共价有机框架（cofs）是新一类的有机晶态聚合物，具有高度有序的结构和永久的孔隙度。依赖于单体不同的拓扑结构，cof 可以分为二维（2d）cofs和三维 (3d) cofs。特别地，2d cofs因其具有扩展的平面内π共轭，拓扑有序柱状π阵列，高的结晶度，大的比表面积，和可调的孔隙，被视为构建功能性 ... WebFeb 25, 2024 · In this paper, we propose a hybrid acid/alkali all-COFs battery by coupling pyrene-4,5,9,10-tetraone based COF cathode with anthraquinone based COF anode. In such a hybrid acid/alkali all-COFs battery, the cathodic COF favorably works in acid with a relatively positive potential, while the anodic COF preferably runs in alkali with a relatively ... WebJun 1, 2024 · The structures and pores of COFs are mainly predetermined through geometric matching of the building units used to form polygonal skeletons. The shapes of the polygons and the pore sizes depend on the geometries and dimensions of the knots and linkers [28].For example, condensation of a building unit of C 3-symmetry with a linear … brightheart and swiftpaw
