Aromaticity is one of chemistry’s oldest concepts to describe the behavior of molecules. Chemists created it 150 years ago to help visualize and explain the bonding, structure, and reactivity of ...

In the January/February issue of the magazine American Scientist, Chemistry Nobel Laureate Roald Hoffmann took exception to scientists applying the concept of aromaticity beyond organic molecules to ...

Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar ...

The concept of aromaticity underpins much of modern organic chemistry, describing the unusual stability and reactivity of cyclic molecules whose π-electrons are delocalised over a planar framework.

In 1862, a chemist nodded off in front of a fire and began to dream. August Kekulé had been pondering the most pressing question in his field at the time: what was the chemical structure of a curious ...

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 ...

Researchers found that antiaromatic planar norcorrole molecules can form close face-to-face interactions to give structures with increased aromaticity. This behavior is quite different from that of ...
