“…Post‐modification is another important strategy to tailor the properties of COFs materials. [ 98,99 ] Among various post‐modification methods, implanting active guest species (small molecules or polymers) into the porous hosts has been demonstrated as an efficient tactic to enhance the electrical conductivity. For example, tetrathiafulvalene (TTF) is featured with π‐electron‐donating abilities and exhibits excellent performance in the field of organic conducting materials.…”

energy-storage systems with high specific energy, long lifespan, and excellent safety. [5][6][7] Among them, the rechargeable secondary batteries have been demonstrated as the most promising candidate for electricity storage and utilization. [8][9][10][11] As one of the most popular batteries, lithium-ion batteries (LIBs) have found immense success in consumer electronics and electric vehicles, and are under the consideration for energy-storage power stations. [12][13][14] However, the commercial LIBs based on transition metal-based inorganic compounds have encountered a bottleneck. [15][16][17] The charge storage of inorganic electrode materials is governed by the oxidation-state variation of transition metal centers and achieved a charge balance with the insertion of counterions. [18] Restricted by crystal lattice and structure stability, the size and valence of counterions are required to match the crystal structures, which severely limit further improvement of energy density. [19][20][21] Clearly, these factors intrinsically weaken the versatility of inorganic materials. For instance, the similar electrode materials, which are successful in LIBs, are not suitable for other alkali ions batteries. [22][23][24] Additionally, from the viewpoint of economical and renewable factors of mineral resources, the existing LIBs based on transition metals (e.g., cobalt, nickel, and manganese) are difficult to meet the requirement of large-scale energy storage. [25] Nowadays, various demands have been raised up for the state-ofthe-art batteries, not only in the enhancement of cycle life, fast charging, and safety, but also in the focus of cost, lightweight, pollution-free, and environmental benign. [26,27] Under this background, researchers gradually shift their studies on novel batteries system and electrode materials. [28][29][30][31] Among them, explorations on the possibility of using organic compounds as potential alternatives of current inorganic electrode materials have never been stopped. [32,33,66] Organics have been demonstrated as promising electrode candidates due to their variety, sustainability, relatively low cost, and environmental friendliness. [34][35][36] The structural diversity implies that the richness of organic materials will provide abundant options and room in this field. The molecule engineering means that the electrochemical properties of organic electrodes can be rationally tuned with different functional groups, which exhibits a good designability of organic materials. These important features allow various designable synthetic routes and convenient functionalization. Although organic electrode materials are endowed with many advantages, their development and Covalent-organic frameworks (COFs), featuring structural diversity, framework tunability and functional versatility, have emerged as promising organic electrode materials for rechargeable batteries and garnered tremendous attention in recent years. The adjustable pore configuration, coupled with the functionalization of frameworks through ...

“…The rich chemistry and the high reactivity of the amine groups make TGCl an ideal ionic monomer for the synthesis of IPOFs. The structure of IPOF-Cl was studied by infrared (IR), solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy, and powder X-ray diffraction (XRD). The strong bands at 1617 cm −1 and 1292 cm −1 displayed in the IR spectrum can be assigned to CvC and C-N stretching, respectively ( Fig.…”

“…[8][9][10][11][12] In addition, the rich organic groups in POFs enable facile modification on the surface, offering an opportunity for the functionalization of POFs. 13 In this context, the synthetic diversity and the principles of reticular chemistry allow the construction of novel POFs with predesigned structures and tailored properties for various applications. [14][15][16][17][18][19][20][21] Recently, a few examples of POFs consisting of ionic frameworks and counter-ions have been reported.…”
