Oct 23, 2024 · The new porous material for capturing carbon dioxide, called a covalent organic framework (COF), has hexagonal channels decorated with polyamines that efficiently bind carbon dioxide molecules (blue and orange balls) at concentrations found in ambient air.

Oct 29, 2020 · A new covalent organic framework uses boron and phosphorus to make complex connections. This new COF is composed of repeating borophosphonate cubes linked at the vertices. O = red; B = pink; P = orange.

Jan 2, 2025 · Herein, to show one effective approach to settle the dilemma of balancing the advantages and disadvantages of 2D vs. 3D COFs, we report a new class of COFs that can achieve the single-crystal size...

Nov 25, 2024 · COF-999 has demonstrated remarkable performance, capturing significant amounts of CO2 from open air and maintaining its efficacy over 100 adsorption-desorption cycles. “It is very stable both chemically and thermally, and can be …

Dec 4, 2024 · Scientists in California have created a new material, called COF-999, which can remove large amounts of carbon dioxide (CO2) from the air. The fluffy yellow powder works faster than other materials and can be used over and over again.

Mar 10, 2025 · In 2024, Tao Zhang from the Chinese Academy of Sciences in Ningbo and colleagues reported an interesting new approach to transform imine-linked COFs into sp 2-carbon-linked COFs. Synthesing an olefin-linked COF without using a transformation is challenging, as the robust olefin bonds hindered the self-correction of the polymerisation process ...

Mar 15, 2025 · The discovery of new linkages for COF-based compounds to achieve chemically stable and π-conjugated frameworks is considered by researchers.

Dec 5, 2022 · To this end, researchers have now developed TUS-84, the first 3D COF with a unique scu-c network structure, with enormous potential in drug delivery and clean energy.

Feb 10, 2025 · In a paper published in Nature, researchers at the University of California, Berkeley outline how COF-999, a strong covalent organic framework they created with colleagues in Chicago and Germany, can capture carbon dioxide out of open air.

New COFs created using a new method by Yaghi Group researchers at the University of California, Berkeley opens the door for organic frameworks with higher connectivity and complexity than ever before.
