“…Combining with precise design of accessible redox centers, abundant 2D COFs with favored conductivity of graphene derivatives or CNTs forming hybrid materials would be an advantage for applications in batteries. [12,244] Chen and co-workers designed and synthesized a microporous framework PIBN and its graphene nanocomposites PIBN-G (Figure 15e). [245] 2D graphene facilitated the diffusion and access of electrolyte into its abundant redox carbonyl groups, considering that the charge transfer resistance of the composite (169.4 Ω) was obviously smaller than that of PIBN (280.2 Ω) (Figure 15f).…”

Covalent–organic frameworks (COFs) are especially interesting and unique as their highly ordered topological structures entirely built from plentiful π‐conjugated units through covalent bonds. Arranging tailorable organic building blocks into periodically reticular skeleton bestows predictable lattices and various properties upon COFs in respect of topology diagrams, pore size, properties of channel wall interfaces, etc. Indeed, these peculiar features in terms of crystallinity, conjugation degree, and topology diagrams fundamentally decide the applications of COFs including heterogeneous catalysis, energy conversion, proton conduction, light emission, and optoelectronic devices. Additionally, this research field has attracted widespread attention and is of importance with a major breakthrough in recent year. However, this research field is running with the lack of summaries about tailorable construction of 2D COFs for targeted functionalities. This review first covers some crucial polymeric strategies of preparing COFs, containing boron ester condensation, amine‐aldehyde condensation, Knoevenagel condensation, trimerization reaction, Suzuki CC coupling reaction, and hybrid polycondensation. Subsequently, a summary is made of some representative building blocks, and then underlines how the electronic and molecular structures of building blocks can strongly influence the functional performance of COFs. Finally, conclusion and perspectives on 2D COFs for further study are proposed.

“…The performance of TpCOF was further enhanced by the formation of hybrid materials with conductive additives, [ 81 ] allowing for a higher amount of redox‐active centers to be reached by electrons. The hybrid materials were formed by the growth of poly(3,4‐ethylenedioxythiophene) (PEDOT), a conductive polymer in the pores of the COF, [ 82 ] or by the growth of the COF on the surface of conductive carbon materials such as nanotubes, [ 83 ] or graphene aerogels. [ 84 ] A TpCOF containing smaller quinone functionalities, reported by Banerjee et al., which benefited from stabilization via intraCOF hydrogen bonding, showed increased capacity with 416 F g –1 at 0.5 A g –1 .…”

The quest for more efficient ways to store electrical energy prompted the development of different storage devices over the last decades. This includes but is not limited to different battery concepts and supercapacitors. However, modern batteries rely on electrochemical principles that often involve transition metals which can for instance suffer from toxicity or limited availability. More sustainable alternatives are needed. This sparked the search for organic electrode materials. Nevertheless, compared to their inorganic counterparts, organic electrode materials remain less intensely investigated. Besides the often more complicated electrochemical principles, one likely reason for that are the complex synthetic skills required to develop novel organic materials. Here we review materials synthesized by an old and comparably simple reaction from the field of organic chemistry, namely Schiff‐base formation. This reaction can often yield materials under relatively mild conditions, making them especially interesting for the formation of sustainable electrodes. The main weakness of Schiff‐base materials, susceptibility to hydrolysis, is of limited concern in most of the battery systems as they mostly anyways require water‐free conditions. This review gives an overview of some selected nanomaterials obtained from Schiff‐base formation as well as their carbonized derivatives which are of interest for energy storage. Firstly, the general chemistry of Schiff‐bases is introduced, followed by an in‐depth survey of the most important breakthroughs in the formation of organic battery electrodes that involve materials based on Schiff‐base reaction. Lastly, an outlook considering the main hurdles as well as future perspectives of this research area is given.

“…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. [22][23][24][25][26] Although the ionic POFs (IPOFs) usually have moderate surface areas due to the pore-blocking effect by the counter-ions, they demonstrate several unique advantages compared to their neutral analogs.…”
