Apr 13, 2007 · Three-dimensional covalent organic frameworks (3D COFs) were synthesized by targeting two nets based on triangular and tetrahedral nodes: ctn and bor.

Abstract: Three-dimensional covalent organic frameworks (3D COFs) were synthesized by targeting two nets based on triangular and tetrahedral nodes: ctn and bor.

Dec 22, 2015 · Crystallinity and porosity are of central importance for many properties of covalent organic frameworks (COFs), including adsorption, diffusion, and electronic transport. We have developed a new method for strongly enhancing both aspects through the introduction of a modulating agent in the synthesis.

Mar 15, 2016 · Covalent organic frameworks, COFs, and their derived sub-groups based on auto-assembly of exclusively aromatic units, PAFs, are emerging into the advanced materials field due to their high free porous volume, structural regularity, robustness, hydrothermal stability, and functional variety.

The organometallic host–guest chemistry of porous covalent organic frameworks is explored by vapour phase infiltration of volatile organometallic precursors; namely, [Fe (η5-C5H5)2], [Co (η5-C5H5)2], and [Ru (cod) (cot)]. The unique arrangement of ferrocene molecules inside COF-102 is driven by π–π (host–guest)

Dec 18, 2018 · The first 3D COFs, COF-102, COF-103, COF-105, and COF-108 were synthesized from the self-condensation of boronic acids into boroxine rings and co-condensation with catechol into boronate...

Jan 14, 2014 · Here we elaborate this approach by demonstrating that monofunctional arylboronic acids serve as effective truncation/functionalization agents for COF-102, a boroxine-linked 3D network derived from the dehydration of a tetrahedral tetrakis(boronic acid) monomer.

COF-102 and COF-103 both exhibit impressive CO 2 capacities at 55 bar, with COF-102 achieving 1200 mg g-1 and COF-103 closely following at 1190 mg.g-1, coupled with very high surface areas of 3620 m 2.g-1 and 3530 m².g-1 respectively, indicating their potential for high-efficiency CO 2 capture and storage in high-pressure environments ...

COF-102内部二茂铁分子的独特排列是由pi-pi（宿主-客体）相互作用驱动的，并复制了框架对称性。 通过气相渗透挥发性有机金属前体，探索了多孔共价有机骨架的有机金属主客体化学。 即 [Fe（eta（5）-C（5）H（5））（2）]， [Co（eta（5）-C（5）H（5））（2）]和 [Ru（ cod）（cot）]。 COF-102内部二茂铁分子的独特排列是由pi-pi（宿主-客体）相互作用驱动的，并复制了框架对称性。

Apr 1, 2025 · Separation mechanism of COF nanofiltration membranes. COFMs, as a class of porous separation membranes, utilize mechanisms such as physical size exclusion (Fig. 2d) and chemical interactions ...
