“…It is worth mentioning that the aforementioned organic materials typically exhibit an amorphous nature. In contrast, crystalline covalent organic frameworks (COFs) have demonstrated the ability to combine porosity with their crystallinity. − Throughout the progression of COFs, synthetic chemistry has been demonstrated to play a crucial role in the development of the structures, connectivity, and functionalities of COFs.…”

Carboxylation of amines is an important route to obtain amino acids. Herein, we have reported the synthesis and characterizations of a new COF/gC 3 N 4 composite which acted as a heterogeneous photocatalyst for the carboxylation of unprotected indoles and N-Bocbenzyl amines. We have used SnO 2 nanoparticles as the cocatalyst and CO 2 as the carbon source under visible light irradiation. This gave a range of carboxylated products both with unprotected indoles and N-Bocbenzylamines with high yield. Control experiments gave the optimum reaction conditions for this photocatalytic carboxylation. Light dependency of this reaction was confirmed by altering the intensity of light. Here, we have synthesized two different catalysts, TpBpy and Tz COF, and the gC 3 N 4 heterojunction which showed excellent photocatalytic activity. The photocatalysts, COF/gC 3 N 4 , are recyclable and reusable for several cycles without a significant loss in performance. The synthesis of a drug compound Clopidogrel and drug formation unit Tirof iban is demonstrated with these photocatalytic protocols.

Covalent organic frameworks (COFs) are porous structures emerging as promising electrode materials due to their high structural diversity, controlled and wide pore network, and amenability to chemical modifications. COFs are solely composed of periodically arranged organic molecules, resulting in lightweight materials. Their inherent properties, such as extended surface area and diverse framework topologies, along with their high proclivity to chemical modification, have positioned COFs as sophisticated materials in the realm of electrochemical energy storage (EES). The modular structure of COFs facilitates the integration of key functions such as redox‐active moieties, fast charge diffusion channels, composite formation with conductive counterparts, and highly porous network for accommodating charged energy carriers, which can significantly enhance their electrochemical performance. However, ascribing intricate porosity and redox‐active functionalities to a single COF structure, while maintaining long‐term electrochemical stability, is challenging. Efforts to overcome these hurdles embrace strategies such as the implementation of reversible linkages for structural flexibility, stimuli‐responsive functionalities, and incorporating chemical groups to promote the formation of COF heterostructures. This review focuses on the recent progress of COFs in EES devices, such as batteries and supercapacitors, through a meticulous exploration of the latest strategies aimed at optimizing COFs as advanced electrodes in future EES technologies.

Eco‐friendly and efficient energy production and storage technologies are highly demanded to address the environmental and energy crises. Porous organic polymers (POPs) are a class of lightweight porous network materials covalently linked by organic building blocks, possessing high surface areas, tunable pores, and designable components and structures. Due to their unique structural and compositional advantages, POPs have recently emerged as promising electrode materials for energy storage devices, particularly in the realm of supercapacitors and ion batteries. In this work, a comprehensive overview of recent progress and applications of POPs as electrode materials in energy storage devices, including the structural features and synthesis strategies of various POPs, as well as their applications in supercapacitors, lithium batteries, sodium batteries, and potassium batteries are provided. Finally, insights are provided into the future research directions of POPs in electrochemical energy storage technologies. It is anticipated that this work can provide readers with a comprehensive background on the design of POPs‐based electrode materials and ignite more research in the development of next‐generation energy storage devices.
