Circularly conjugated compounds with 4n+2 pi-electrons are known as aromatic compounds. They are generally stable and are therefore found in our surroundings. On the other hand, anti-aromatic ...

Pushing the limits of size constraints in chemistry, an 8-nanometer 18-porphyrin nanoring (c-P18) becomes the largest known ...

The term aromaticity was initially introduced to describe the properties of molecules with special aromatic odor, such as benzene, and now is considered as one of the most important concepts in ...

The novel compound is a new chapter in a story that began in 1825, when English scientist Michael Faraday first isolated benzene from gas lights. Benzene would later be identified as one of a class of ...

Scientists found that four hydrocarbon molecules, known for their internal ring structure, have a lower threshold for the release of excess energy than molecules without a similar ring structure, ...

A version of this story appeared in Volume 96, Issue 41 Saito explains that selenium’s large size allows overlapping σ orbitals from the six atoms to create aromaticity. The phenylselenyl groups ...

Macrocyclic hydrocarbons formally made up of alternating single and double bonds (annulenes) are of interest, since theory predicts such compounds to be aromatic, provided their carbon skeleton can ...

THE recently published work on the crystal structures of anthracene, chrysene and dibenzanthracene 1 has shown that the graphitic structure, with all the atoms lying in one plane, and an interatomic ...
