Two high-quality single-crystal sp²c-COFs have been developed, demonstrating the generality of this approach. This work ...

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 ...

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

About 90 years ago, American chemical engineer Linus Pauling proposed a unique concept. He suggested that two atoms don’t ...

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 ...

Covalent bonding close covalent bondA bond between atoms formed when atoms share electrons to achieve a full outer shell of electrons. leads to the formation of substances with different types of ...

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 ...

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 drying procedure using supercritical carbon dioxide gives greater access ... offered by frameworks based on coordination bonds and covalent bonds. Indeed, new classes of highly porous frameworks ...
