2005年11月18日 · Their crystal structures are entirely held by strong bonds between B, C, and O atoms to form rigid porous architectures with pore sizes ranging from 7 to 27 angstroms. COF-1 and COF-5 exhibit high thermal stability (to temperatures up to 500° to 600°C), permanent porosity, and high surface areas (711 and 1590 square meters per gram ...

2019年4月21日 · cof-1是二维六方的平面拓扑，层之间采取ab堆积方式，cof-5也是二维六方的平面拓扑，层间采取完全重叠的aa堆积模式。 图1. COF-1和COF-5的合成与结构式

High-pressure XRD and Raman experiments with mesitylene-filled (COF-1-M) and empty-pore COF-1 demonstrate partial amorphization and collapse of the framework structure above 12–15 GPa. The ambient pressure structure of COF-1-M can be reversibly recovered after compression up to 10–15 GPa.

2005年，MOFs材料的提出者，Yaghi教授的一篇Science正式宣告了COFs材料的问世。其研究团队成功制备出COF-1，COF-5两个二维材料（图1），并通过氮气吸脱附实验得到了其孔径，初步显示了COFs材料在吸附方面的应用。

The best COF in terms of total volume of CH 4 per unit volume COF adsorbent is COF-1, which can store 195 v/v at 298 K and 30 bar, exceeding the U.S. Department of Energy target for CH 4 storage of 180 v/v at 298 K and 35 bar. The best COFs on a delivery amount basis (volume adsorbed from 5 to 100 bar) are COF-102 and COF-103 with values of 230 ...

摘要cof-1 具有由苯和 b 组成的刚性二维层结构3氧3环和层之间的弱范德华键。合成的 cof-1 结构包含被溶剂分子占据的孔。真空退火后获得高表面积的空孔结构。均三甲苯填充 (cof-1-m) 和空孔 cof-1 的高压 xrd 和拉曼实验表明，在 12-15 gpa 以上时，骨架结构发生部分非晶化和塌陷。

2025年2月24日 · The visible photocatalytic hydrogen evolution rate reaches 126 mmol g–1 h–1 for the simplest β-ketoenamine-linked COF and 350 mmol gCOF–1 h–1 for SiO2@COF with minimal Pt cocatalysts.

The electron-deficient B atoms in COF-1 accepted electrons from S x 2–, and electron-rich O atoms donated electrons to Li +, leading to the strong chemical interaction between polysulfides and COF-1.

2022年4月6日 · Urea-COF-1 (also known as COF-117; ref. 42) was first synthesized via a Schiff-base condensation reaction of 1,1'-(1,4-phenylene)diurea with 1,3,5-triformylphloroglucinol in a mixture...

2023年9月27日 · cof-1和cof-5. 二、有机共价材料制备及表征. 截至目前cofs材料已经发展到上百种，虽然cofs材料种类众多，但是在反应的选择上多数集中在四种可逆反应上：硼酸三聚、硼酸酯化、腈类自聚、希夫碱反应这四类[4]。
