2023年6月20日 · Herein, we report the first case of constructing a 3D COF, termed COF-904, through interdigitating 2D hcb nets, which was formed via [3+2] imine condensation reactions by the use of 1,3,5-triformylbenzene and 2,3,5,6-tetramethyl-1,4-phenylenediamine.

2023年6月7日 · Linear dialdehydes and piperazine are condensed at a ratio of 1:2 to construct an aminal linkage, leading to unreported hxl-a (KUF-2) and quasi-hcb (KUF-3) structures. Notably, KUF-3 displays top-tier C 2 H 6 /C 2 H 4 selectivity and C 2 H 6 uptake at 298 K, outperforming most porous organic materials.

2022年4月13日 · With high thermal and chemical resistances, the COF-packed HPLC columns show excellent performance to provide separation of 10 different polycyclic aromatic hydrocarbons, a group of the most widespread organic environmental pollutants.

2023年8月18日 · X射线单晶结构证实氢键提供了3连接的胺结构单元，形成HOF，即HOF-TPPA，具有hcb拓扑结构。 HOF和目标COF之间的拓扑相似性促进了在机械研磨下从HOF-TPPA到COF（同拓扑COF-TPPA-1、COF-TPPA-2和COF-TPPA-3）的转变。

2018年12月10日 · Here we present a methodology for high-throughput construction of covalent organic frameworks (COFs) based on materials genomics strategy, in which a gene partition method of genetic structural...

2023年8月18日 · We reported the directed structural transformation of a hydrogen-bonded organic framework (HOF) to covalent organic frameworks (COFs) via a mechanochemical drive for the first time. The X-ray single crystal structure confirmed that the hydrogen bonds afford a 3-connected amine building unit forming a HOF, namely, HOF-TPPA, with a hcb topology ...

2024年11月7日 · 在这项研究中，设计了三种拓扑结构明显不同的 π 共轭 2D sp 2 碳连接 COF （hcb、sql 和 hxl），以研究拓扑结构对水和氧中 H 2 O 2 整体光合作用的拓扑效应。

2020年6月1日 · Covalent organic frameworks (COFs) are an emerging class of crystalline porous polymers with pre-designed structures and tailored compositions. The adjustable porosities, high thermal and chemical stabilities, tunable functionalities and flexibility in installing catalytic active sites translate COFs into highly promising catalytic materials.

2021年5月15日 · Covalent organic frameworks (COFs), constructed with the light atoms such as carbon, nitrogen, oxygen, borane etc. via covalent bonds, represent a promising class of structurally ordered, highly crystalline functional porous materials possessing a large surface area to …

填充 cof 的 hplc 色谱柱具有高耐热性和耐化学性，表现出出色的性能，可分离 10 种不同的多环芳烃，这是一组最普遍的有机环境污染物。 因此，五顶点阿基米德镶嵌的实施为设计具有新拓扑结构的 COF 提供了一种策略，并为扩展 COF 材料的独特特性铺平了新的道路。
