Apr 10, 2023 · We selected an as-synthesized COF-301 (termed COF-301-S) to prove the single crystallinity and resolve the atomic structure with single-crystal X-ray diffraction (XRD; Supplementary Fig. 3...

Jul 14, 2023 · We show that symmetry-asymmetry tautomerisation from diiminol to iminol/cis-ketoenamine can be stabilised and switched in a crystalline, porous, and dynamic 3D COF (dynaCOF-301) through...

Using accurate quantum mechanical (QM) methods, we studied the H2 binding energy to 48 compounds based on various metalated analogues of five common linkers for covalent organic frameworks (COFs).

Jan 30, 2019 · Based on the results of PXRD patterns and 1 H NMR spectra, the COF-320-to-COF-300 transformation was successfully achieved, and an efficiency as high as 89% was attained.

Jan 24, 2025 · As a result, COF-301-PL demonstrates excellent fluidity and porosity at room temperature. The intrinsic flexibility of COF-301, derived from its distorted tetrahedral building blocks and interpenetrating networks, enables dynamic pore expansion upon CO 2 filling.

Jul 6, 2018 · Single crystals of COFs amenable to x-ray diffraction characterization have not been reported. Here, we developed a general procedure to grow large single crystals of three-dimensional imine-based COFs (COF-300, hydrated form …

Jan 25, 2023 · Here, a highly crystalline three-dimensional hydroxylated covalent organic frameworks (denoted by COF-301) with tetra (4-anilyl)methane (TAM) and 2,5-dihydroxyterephthalaldehyde (DHTA) as building units was constructed and proposed as adsorbent for solid phase extraction (SPE) of glucocorticoids.

Mar 27, 2024 · Three-dimensional single-crystal COF-301 (SCOF-301) with an intramolecular H-bond-induced excited-state intramolecular proton-transfer effect is selected as a proof-of-concept SCOF.

Feb 27, 2020 · Two reported three-dimensional covalent organic frameworks (3D-COFs), COF-300 and COF-301, which have hierarchical porous structures and large pore volumes, were synthesized and employed as host materials for lithium-sulfur batteries.

Covalent organic frameworks (COFs) have emerged as highly crystalline porous organic materials and proven to be potential candidates for various interesting applications, such as gas adsorption and separation, catalysis, energy storage, and sensing.
