2023年4月10日 · 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 and...

2023年7月14日 · 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...

cof-301 Paper: A Covalent Organic Framework that Exceeds the DOE 2015 Volumetric Target for H 2 Uptake at 298 K Authors: J. L. Mendoza-Cortes, H. Furukawa, W. A. Goddard III, and O. M. Yaghi

2025年1月24日 · COF-301 was selected because of its ultra-micropore window (7.1 Å) and 7-fold interpenetrated flexible structure, which prevents the penetration of PEG-Im-Si(OCH 3) 3 coronas (18.8 Å) and PEGS canopies (50.5 Å), thus maintaining PL porosity. Molecular dynamics (MD) simulations show that strong electrostatic interactions between the cationic ...

2023年4月18日 · 他们选择了一个正常合成的cof-301（称为cof-301-s）来证明单晶度，并通过单晶x射线衍射（xrd）来解析其原子结构。cof-301-s是单晶，具有i41/a（a = 26.434(4) Å, c = 7.5876(15) Å）的四方空间群和7重互穿。

2023年1月25日 · 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.

通过对三维单晶cof-301（scof-301）进行荧光响应实验，发现不同晶体尺寸的cof对乙醇、苯和氨的荧光响应机制存在差异。小型单粒子scof-301表现出更灵活的结构，主要受形变影响；随着晶体尺寸增大，结构变得更加刚性，竞争性h键位的影响开始主导荧光响应。

2020年2月27日 · 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.

使用单晶x射线衍射证明了cof-301-s（合成的cof-301中挑选出）的单晶性并解析其原子结构。 结果表明COF-301-S是钻石拓扑结构，整个晶体由七个钻石拓扑网络互穿而成，具有I41/a的四边形空间群(a = 26.434(4) Å, c = 7.5876(15) Å)，其中每个TAM分子连接到四个DHTA（图5a）。

Here we report a strategy to produce single-crystal imine-linked COFs in aqueous solutions under ambient conditions using amphiphilic amino-acid derivatives with long hydrophobic chains.
