The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen. Each redox state of carbon (Fig. 2) is associated with a class ...

Two high-quality single-crystal sp²c-COFs have been developed, demonstrating the generality of this approach. This work addresses the bottleneck in synthesizing single-crystal COFs and provides ...

The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent bonds The intermolecular forces vary between molecules, so different organic ...

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms form a double bond because there is a strong enough attraction in both directions and room for the ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent ...

The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent bonds The intermolecular forces vary between molecules, so different organic ...

Carbon nanotubes are essentially a sheet of graphene rolled up on itself. To join a nanotube with other molecules, it is ...

Chinese scientists proposed a novel imine-to-olefin transformation strategy to synthesize single-crystal sp² carbon-linked covalent ... through strong covalent bonds. COFs have numerous ...

Researchers have developed a new chemical tool that could help lower the cost of prescription medications. The tool, called AshPhos, is a ligand, or molecule, that makes it easier to create special ...
