Three-dimensional covalent organic frameworks (3D COFs) were synthesized by targeting two nets based on triangular and tetrahedral nodes: ctn and bor.

Abstract: Three-dimensional covalent organic frameworks (3D COFs) were synthesized by targeting two nets based on triangular and tetrahedral nodes: ctn and bor.

The organometallic host–guest chemistry of porous covalent organic frameworks is explored by vapour phase infiltration of volatile organometallic precursors; namely, [Fe(η5-C5H5)2], [Co(η5-C5H5)2], and [Ru(cod)(cot)]. The unique arrangement of ferrocene molecules inside COF-102 is driven by π–π (host–guest)

2016年3月15日 · Covalent organic frameworks, COFs, and their derived sub-groups based on auto-assembly of exclusively aromatic units, PAFs, are emerging into the advanced materials field due to their high free porous volume, structural regularity, robustness, hydrothermal stability, and functional variety.

2014年1月14日 · Here we elaborate this approach by demonstrating that monofunctional arylboronic acids serve as effective truncation/functionalization agents for COF-102, a boroxine-linked 3D network derived from the dehydration of a tetrahedral tetrakis(boronic acid) monomer.

COF-102 and COF-103 both exhibit impressive CO 2 capacities at 55 bar, with COF-102 achieving 1200 mg g-1 and COF-103 closely following at 1190 mg.g-1, coupled with very high surface areas of 3620 m 2.g-1 and 3530 m².g-1 respectively, indicating their potential for high-efficiency CO 2 capture and storage in high-pressure environments ...

COF-102内部二茂铁分子的独特排列是由pi-pi（宿主-客体）相互作用驱动的，并复制了框架对称性。 通过气相渗透挥发性有机金属前体，探索了多孔共价有机骨架的有机金属主客体化学。 即 [Fe（eta（5）-C（5）H（5））（2）]， [Co（eta（5）-C（5）H（5））（2）]和 [Ru（ cod）（cot）]。 COF-102内部二茂铁分子的独特排列是由pi-pi（宿主-客体）相互作用驱动的，并复制了框架对称性。

2008年9月24日 · 通过使用基于第一性原理计算参数化的精确分子力学力场，可以在没有实验输入的情况下正确预测共价有机框架 COF-102 的网络拓扑。由于较低的空间应变，ctn 结构在热力学上比 bor 拓扑结构优先 11.2 kcal mol(-1)。详细分析了该菌株的来源。

西安齐岳生物供应的COF-105、COF-108、 COF-102、COF-103是一种共价有机骨架材料，共价有机骨架材料的英文Covalent Organic Frameworks（简称COFs）。 有机构建单元通过共价键连接在一起，形成具有周期性结构的多孔骨架。 报道了四例三维COFs, 其设计的关键在于选择了具有Td对称性的正四面体构型单体：四苯基甲烷硼酸（TBPM和TBPS），跟C3对称性的三角形构型的多酚化合物HHTP组合， TBPM和TBPS自缩聚形成COF-102和COF-103, TBPM和TBPS分别 …

Atomistic simulations have been performed on CO 2 storage in covalent-organic frameworks (COFs) including 3D (COF-102, COF-103, COF-105, and COF-108), 2D (COF-6, COF-8, COF-10) and 1D (COF_NT) structures. Compared to 2D and 1D COFs, 3D COFs have substantially larger free volume, porosity and surface area.
