Published: June 3, 2021

Abstract Covalent organic frameworks (COFs) have emerged as an exciting new class of porous materials constructed by building blocks via dynamic covalent bonds. They been extensively explored potentially superior candidates for electrode materials, electrolytes, and separators, due to their tunable chemistry, tailorable structures, well‐defined pores. These features enable rational design targeted functionalities, facilitate the penetration enhance ion transport. This review provides in‐depth summary recent progress in development COFs diverse battery applications, including lithium‐ion, lithium–sulfur, sodium‐ion, potassium‐ion, lithium–CO 2 , zinc‐ion, zinc–air batteries, etc. comprehensive synopsis pays particular attention structure chemistry novel strategies that implemented improve performance. Additionally, current challenges, possible solutions, potential future research directions on batteries are discussed, laying groundwork advances this material.

Integrating Bifunctionality and Chemical Stability in Covalent Organic Frameworks via One-Pot Multicomponent Reactions for Solar-Driven H₂O₂ Production

Journal of the American Chemical Society, Journal Year: 2023, Volume and Issue: 145(5), P. 2975 - 2984

Published: Jan. 25, 2023

Multicomponent reactions (MCRs) can be used to introduce different functionalities into highly stable covalent organic frameworks (COFs). In this work, the irreversible three-component Doebner reaction is utilized synthesize four chemically quinoline-4-carboxylic acid DMCR-COFs (DMCR-1-3 and DMCR-1NH) equipped with an acid-base bifunctionality. These show superior photocatalytic H2O2 evolution (one of most important industrial oxidants) compared imine COF analogue (Imine-1). This achieved sacrificial oxidants but also in pure water under oxygen or air atmosphere. Furthermore, high photostability, durability, recyclability. MCR-COFs thus provide a viable materials' platform for solar chemical energy conversion.

Facile construction of fully sp2-carbon conjugated two-dimensional covalent organic frameworks containing benzobisthiazole units

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Jan. 10, 2022

Abstract Developing a facile strategy for the construction of vinylene-linked fully π -conjugated covalent organic frameworks (COFs) remains huge challenge. Here, versatile condition Knoevenagel polycondensation constructing 2D COFs was explored. Three new examples ( BTH-1 , 2 3 ) containing benzobisthiazoles units as functional groups were successfully prepared under this and mild condition. The electron-deficient benzobisthiazole cyano-vinylene linkages both integrated into conjugated skeleton acted acceptor moieties. Interestingly, we found highly ordered D-A system is favorable photocatalytic activity. BTH-3 with benzotrithiophene donor strong effect exhibited an attractive HER 15.1 mmol h −1 g visible light irradiation.
