COFs and their cousin materials, metal organic frameworks (MOFs), are porous three-dimensional crystals with extraordinarily large internal surface areas that can absorb and store enormous quantities of targeted molecules. Invented by UC Berkeley's Professor Omar Yaghi, COFs and MOFs consist of molecules (organics for COFs and metal-organics for MOFs) that are stitched into large and extended netlike frameworks whose structures are held together by strong chemical bonds. Such frameworks show great promise for, among other applications, carbon sequestration.

Paving the way for more efficient hydrogen cars

December 7, 2018

New hydrogen-powered vehicle research

Hydrogen-powered vehicles emit only water vapor from their tailpipes, offering a cleaner alternative to fossil-fuel-based transportation. But for hydrogen cars to become mainstream, scientists need to develop more efficient hydrogen-storage systems. Now, a group of scientists reporting in ACS' Chemistry of Materials have used metal–organic frameworks (MOFs) to set a new record for hydrogen storage capacity under normal operating conditions.

Molecular decoration determines origin of MOF acidity

November 29, 2018


Researchers have pinpointed the strong acid site of a sulfated-zirconium MOF catalyst by identifying a specific molecular decoration within its structure. The work could aid studies into solid acid-catalysed reaction mechanisms as well as the development of next-generation solid acid catalysts for many industrial applications.

Yaghi, University of California, “for their fundamental contributions to the development of reticular chemistry”.

Getting a charge out of MOFs

August 24, 2018

metal-organic frameworkUC Berkeley researchers have developed a modular metal-organic framework with the highest electron charge mobilities ever observed. A research team led by Jeffrey Long has developed a technique for making an electrically conductive MOF that could also be used to improve the conductivity of other MOFs.
