Apr 13, 2007 · Atomic connectivity and structure of crystalline products of COF-102 (A), COF-105 (B), and COF-108 (C), based on PXRD and modeling. Hydrogen atoms are omitted for clarity.

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

Dec 18, 2018 · Most early 3D COF structures were formed utilizing boron–oxygen (B–O) linkages. The first 3D COFs, COF-102, COF-103, COF-105, and COF-108 were synthesized from the self-condensation of...

In the case of COF-102, a 3D structure prepared by the auto-condensation of tetra (4-dihydroxyborylphenyl)methane (TBPM) (Scheme 4), an H 2 maximum adsorption capacity of 77 mg g –1 was reported, at 35 bar and 77 K, a result rivalling the best MOFs and other porous structures obtained at similar high pressures, and almost meeting the current ...

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)

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.

Mar 5, 2024 · We report a rapid, room-temperature mechanochemical synthesis of 2- and 3-dimensional boroxine covalent organic frameworks (COFs), enabled by using trimethylboroxine as a dehydrating additive to overcome the hydrolytic sensitivity of boroxine-based COFs.

We demonstrate a tandem truncation–functionalization strategy using the 3D covalent organic framework, COF-102. Allyl groups incorporated within the pore walls were subjected to thiol–ene coupling conditions, achieving high conversions and maintaining the crystallinity and permanent porosity of the parent fr

Jan 5, 2015 · The methane uptakes of six double halogen substituted covalent organic frameworks (COFs) based on COF-102 were simulated with grand canonical Monte Carlo simulation at 298 K and pressure ranges from 1 to 80 bar.

Jan 15, 2021 · The Pd nanoparticles modified COF-102 possessed narrow pore size distribution (2.4 ± 0.5 nm) without any larger metallic aggregation even under 30 wt% Pd loadings, indicating that COF-102 was a good platform for stabilizing monodisperse nanoparticles [126].
