Millimetre-sized single crystals of covalent organic frameworks have been constructed by taking advantage of a reversible dimerization reaction of nitroso groups. Scientists and non-scientists alike ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

Chinese scientists proposed a novel imine-to-olefin transformation strategy to synthesize single-crystal sp² carbon-linked covalent organic frameworks (sp²c-COFs). COFs are crystalline, porous ...
