The large‐scale application of lithium‐sulfur batteries (LSBs) has been impeded by the shuttle effect of lithium‐polysulfides (LiPSs) and sluggish redox kinetics since which lead to irreversible capacity decay and low sulfur utilization. Herein, a hierarchical interlayer constructed by boroxine covalent organic frameworks (COFs) with high Li+ conductivity is fabricated via an in situ polymerization...
It is still a great challenge to explore hydrogen evolution reaction (HER) electrocatalysts with both lower overpotential and higher stability in acidic electrolytes. In this work, an efficient HER catalyst, Ru@COF‐1, is prepared by complexation of triazine‐cored sp2 carbon‐conjugated covalent organic frameworks (COFs) with ruthenium ion. Ru@COF‐1 possesses high crystallinity and porosity, which are...
Efficient detection of aqueous copper ions is of high significance for environmental and human health, since copper is involved in potent redox activity in physiological and pathological processes. Covalent organic frameworks (COFs) have shown advantages in efficient capturing and detecting of copper ions due to their large surface area, robust chemical stability, and high sensitivity, but most of...
Two‐dimensional covalent organic frameworks (2D COFs) offer a designable platform to explore porous polyelectrolyte frameworks with periodic ionic skeletons and uniform pore channels. However, the crystallinity of ionized 2D COF is often far from satisfactory as the electrostatic assembly of structures impedes the ordered layered arrangement. Here, a multivariate synthetic strategy to synthesize a...
2D covalent organic frameworks (COFs) are considered as one kind of the most promising crystalline porous materials for solar‐driven hydrogen production. However, adding noble metal co‐catalysts into the COFs‐based photocatalytic system is always indispensable. Herein, through a simple solvothermal synthesis method, TpPa‐1‐COF, a typical 2D COF, which displays a wide light absorption region, is rationally...
Oxidative stress and local overactive inflammation have been considered major obstacles in diabetic wound treatment. Although antiphlogistic tactics have been reported widely, they are also challenged by pathogen contamination and compromised angiogenesis. Herein, a versatile integrated nanoagent based on 2D reductive covalent organic frameworks coated with antibacterial immuno‐engineered exosome...
The development of highly active carbon‐based bifunctional electrocatalysts for both the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) is highly desired, but still full of challenges in rechargeable Zn–air batteries. Metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have gained great attention for various applications due to their attractive features of structural...
Developing effective electrocatalysts for CO2 reduction (CO2RR) is of critical importance for producing carbon‐neutral fuels. Covalent organic frameworks (COFs) are an ideal platform for constructing catalysts toward CO2RR, because of their controllable skeletons and ordered pores. However, most of these COFs are synthesized from Co‐porphyrins or phthalocyanines‐based monomers, and the available building...
Photodynamic therapy (PDT) of cancers is seriously restricted by tumor hypoxia. In addition to the intrinsic hypoxic microenvironment, continuous photoirradiation further aggravates intratumoral hypoxia, thereby reducing the PDT effect significantly. Oxygen‐independent PDT is recognized as an efficient approach to overcome this issue. Herein, singlet oxygen (1O2)‐stored covalent organic framework...
Metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) hybrid materials are a class of porous crystalline materials that integrate MOFs and COFs with hierarchical pore structures. As an emerging porous frame material platform, MOF/COF hybrid materials have attracted tremendous attention, and the field is advancing rapidly and extending into more diverse fields. Extensive studies have...
The polymerization of 1,4‐benzenediboronic acid (BDBA) on mica to form a covalent organic framework (COF‐1) reveals a dramatic increase in crystallinity when physically confined by exfoliated graphene. COF‐1 domains formed under graphene confinement are highly geometric in shape and on the order of square micrometers in size, while outside of the exfoliated flakes, the COF‐1 does not exhibit long‐range...
