2025年1月22日 · Our study presents a highly effective approach for precisely ordering metal ion-coordinated COF (M -COF) nanochannels and enhancing the local surface negative charge. This enhancement notably...

2024年12月11日 · In this study, we used tannic acid (TA) as the heterogeneous nucleation site to regulate the reaction-diffusion kinetics for the in situ synthesis of COF thin films with a unique …

2025年2月24日 · Here, we propose a zone crystallization strategy for covalent organic frameworks (COFs) that enhances surface ordering through regulator-induced amorphous-to-crystalline transformation.

2019年12月30日 · Recently, Lai and co-workers synthesized well-defined porous COF, DFP-DHP COF, through a two-step reaction: the first step is the Schiff-base condensation reaction of 1,3,5-triformylpholoroglucinol (TFP) and 9,9-dihexylfluorene-2,7-diamine (DHF), and the next step is an irreversible tautomerism reaction to form a β-ketoenamine structure to ...

2 天之前 · The PXRD patterns for BMTA-TFPM-COF with increasing the temperature from 25 to 600 °C under air. 3) In the initially published version of Supporting Information, the purple curve in Figure S19A (Supporting Information) was incorrect during the combination of multilayer FT-IR results of different samples The revised version of Figure S19A ...

2025年1月13日 · COK-47 exhibited the most stable and lowest COF curve, both compared to other MOFs (Figure 6a) and to 2D materials (Figure 6b). In terms of the promising solid lubricant candidate, not only the value of COF but also the wear rate should be considered.

2025年1月15日 · The asymmetric nanofluidic membrane is prepared by coupling a two-dimensional covalent organic framework (COF) membrane to an anodic aluminum oxide (AAO) nanochannel via hydrogen bonding. The prepared COF/AAO membrane presents selective ion transport due to the asymmetric structure and anion selectivity of COF.

Covalent organic frameworks (COFs) are an emerging class of highly ordered porous polymers with many potential applications. They are currently designed and...

2025年1月24日 · Molecular dynamics (MD) simulations show that strong electrostatic interactions between the cationic corona-canopy species and PEGS anions are key to the dispersion and stability of the porous host. As a result, COF-301-PL demonstrates excellent fluidity and porosity at room temperature.

2025年3月1日 · This work presents a novel approach for accurately predicting the gas transport properties of covalent organic framework (COF) membranes using a nonequilibrium molecular dynamics (NEMD) methodology called concentration gradient-driven molecular dynamics (CGD-MD). We first simulated the flux of hydrogen (H2) and methane (CH4) across two distinct COF membranes, COF-300 and COF-320, for which ...
