The development of new linkages is one of the most efficient strategies to enrich the diversity of covalent organic frameworks (COFs). Particularly, functional linkages can endow COFs with additional tailored properties besides the building units, which further diversify COFs with desirable functions. Herein, we have developed a new arylamine linkage for the construction of COFs. Two new arylamine‐linked COFs (AAm‐TPB and AAm‐Py) were prepared by condensing cost‐effective dimethyl succinyl succinate (DMSS) with corresponding multitopic amines (TPB‐NH 2 and Py‐NH 2 ). Due to the abundant electroactive diphenylamine moieties in the COF skeletons resembling that of polyaniline (PANI), a state‐of‐the‐art conductive polymer, the pseudocapacitive energy storage performance of AAm‐TPB was further investigated. Remarkably, the AAm‐TPB electrode exhibits a high capacitance of 271 F g −1 with a three‐electrode setup at a discharge rate of 1 A g −1 , which represents one of the highest capacitances among the reported COF‐based electrode materials.
