While today aromaticity has nothing to do with odour (instead defined as a cyclic compound), for chemists of the past their noses were a vital tool for identifying benzene-like compounds.

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 ...

I have encountered a problem with the way the software interprets the structure of a bicyclic molecule, leading to incorrect results in the output. Specifically, the molecule in question consists o ...

Researchers have unravelled the reason azulene breaks a key fluorescence rule: the molecule’s switch to anti-aromaticity and back to aromaticity in its excited states. Azulene is an aromatic molecule ...

(Anti)aromaticity reveals key to Azulene’s blue light magic “I like theories that are so simple you can easily remember, and then put them to use. We’ve answered the question of why ...

Chemistry One of chemistry's most crucial concepts is in crisis - can we fix it? Our understanding of aromaticity, a concept that underpins life itself, has been thrown into chaos.

It connected the aromaticity of PCHs, fullerenes and 2D periodic materials, and was developed into a generally unified theory for conjugated π systems.

Researchers at Linköping University have used computer simulations to show that stable aromatic molecules can become reactive after absorbing light. The results, published in The Journal of ...

The NICS aromaticity indices of the rings in flexible phenylalanine (Phe), tryptophan (Trp), tyrosine (Tyr), and histidine (His) chiral molecules were analyzed. These molecules have several dozens of ...

Electrophilic aromatic substitution (EAS) reactions are hallmarks of aromaticity. However, the potential of compounds with Möbius aromaticity to undergo EAS has been ignored for a long time. A number ...

Researchers have been trying to find a full definition of aromaticity for almost two centuries, and yet keep discovering new types. Katrina Krämer asks when chemists will get to the bottom of this ...
