2009年3月12日 · A new crystalline porous three-dimensional covalent organic framework, termed COF-300, has been synthesized and structurally characterized. Tetrahedral tetra- (4-anilyl)-methane and linear terephthaldehyde building blocks were condensed to form imine linkages in a material whose X-ray crystal structure shows five independent diamond frameworks.

2023年5月12日 · Here we report a rapid (15 min–5 day) synthesis of hydrated COF-300 colloids ranging in length (251 nm–4.6 μm) with high crystallinity and moderate surface areas (150 m 2 g −1). These materials are characterized by pair distribution function analysis, which is consistent with the known average structure for this material alongside ...

COF-300是一种晶态三维多孔共价有机框架材料，展现出在490°C以下的高热稳定性和永久多孔性，比表面积达到1360 m² g⁻¹，适用于气体存储和分离等领域。

2020年12月1日 · The COF-300 layer can provide the high-efficiency transport pathways for water molecules and simultaneously effective rejection for dye molecules, which is 5–10 times remarkably higher than those of most commercially available NF …

2024年7月1日 · Detailed analysis of the influence of time and temperature on the synthesis of COF-300 showed partial linker degradation but still allowed 3D electron diffraction structure solution using optimized conditions.

新型动态三维共价有机框架材料cof-300，通过扩散梯度转亚胺化协议合成，具有原子级别的构象动态性，能够适应不同客体分子，为研究液体的凝聚态结构提供了新途径。

2018年7月6日 · Here, we developed a general procedure to grow large single crystals of three-dimensional imine-based COFs (COF-300, hydrated form of COF-300, COF-303, LZU-79, and LZU-111). The high quality of the crystals allowed collection of single-crystal x-ray diffraction data of up to 0.83-angstrom resolution, leading to unambiguous solution and precise ...

Herein, we propose a novel electrospraying strategy to prepare high-performance covalent organic frameworks/polydimethylsiloxane (COF/PDMS) hybrid membranes with unique hierarchical microstructure for efficient bio-alcohol recovery. Organophilic COF-300 was synthesized and applied as porous fillers.

2025年2月7日 · 值得注意的是，COF-300即使在280°C也能保持其单晶结构，并能有效吸收熔融态的多环芳烃。 3、结合PXRD和理论计算研究了构象异构体之间的结构转化动力学。 从高能态到低能态的结构转变是一个快速的、能量上有利的过程，而反向转变是一个由浓度梯度驱动的缓慢过程。 Fig. 1 | The schematic representation of the structural transformation of COF-300 …
