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 ...

Saito explains that selenium’s large size allows overlapping σ orbitals from the six atoms to create aromaticity. The phenylselenyl groups donate electron density to the benzene to make ...

Aromaticity, a concept usually used to explain the striking stability and unusual reactivity of certain carbon-based molecules, could inspire the design of new catalysts with novel uses, KAUST ...

First experimental evidence of 3D aromaticity in stacked antiaromatic compounds Date: December 15, 2016 Source: Nagoya University Summary: Researchers found that antiaromatic planar norcorrole ...

Physical Chemistry Pnictogen Ring Boasts Aromaticity Inorganic Chemistry: Anion made solely from phosphorus and nitrogen is stabilized by electron delocalization by Bethany Halford ...
