May 9, 2024 · Here, we report an example of a complete structural rearrangement of a 2D boronate ester COF to a spiroborate linked 3D COF by boron hybridization. This reconstruction is catalyzed by basic environments under solvothermal conditions (Figure 1a).

Photocatalytic covalent organic frameworks (COFs) are popular in the field of biomedical materials and also have potential as antimicrobial materials. Herein, a boron-based COF was used in antibacterial applications innovatively.

Jun 21, 2016 · Our recent mechanistic studies of both boron and imine COF formation reveal major differences: boron COFs seem to crystallize rapidly, whereas a 2D imine system precipitated from solution as an amorphous structure that subsequently crystallized. The appropriate rates of bond formation and exchange are still poorly understood, making the ...

Jan 15, 2023 · This disclosed method endowed the typical COFs with new emissive life and is speculated with the general research concept for all boron-containing COFs. Benefiting from the prominent fluorescent emission in the aggregation state, …

Aug 29, 2019 · Here, we demonstrate that facilitating the N2 accessibility to boron-rich covalent organic frameworks through electrochemical excitation can achieve highly efficient nitrogen reduction activity.

Dec 12, 2023 · Herein, we present the construction of boronic ester-linked COFs through nucleophilic substitution reactions in order to catalyze the CO 2 RR. The inclusion of abundant fluorine atoms within the frameworks enhances their hydrophobicity and subsequently improves water tolerance and chemical stability of COFs.

Mar 10, 2025 · COFs are composed of light elements such as hydrogen, carbon, boron, nitrogen and oxygen. Yaghi’s group published the first 2D COFs in 2005 and the first 3D versions in 2007. Both contained highly reversible boron–oxygen linkages. ... COF-999 was modified after construction to transform the azide groups dangling into its pores into amines ...

Mar 20, 2024 · Covalent organic frameworks (COFs) exhibit excellent antimicrobial properties due to their diversified structures and functionalities. Wang et al. discuss the topology, material types, and antimicrobial mechanisms of COF-based materials, …

Here, an overview is provided on boronic-acid-derived COFs, including synthesis, building block design and mechanism of COF formation, structures and properties, processing and implementation into functional devices, as well as examples of application for which these materials have been studied.

Feb 15, 2025 · For this purpose, zinc/ l -cysteine (ZC) inbuilt pH-sensitive covalent organic framework (COF) decorated two dimensional (2D) layered amino-functionalized (Si) oxidized hexagonal boron nitride (ZC-COF-Si-Oh-BN) container was prepared.
