Excited-state aromaticity refers to the transient stabilisation or destabilisation of cyclic π-electron systems upon photoexcitation. In the electronic ground state many organic compounds obey ...

The installation of trifluoromethyl (CF3) and longer perfluoroalkyl chains on aromatic rings has emerged as a cornerstone of modern organic synthesis, owing to the profound influence of fluorine ...

The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore ...

After nearly 50 years of failed attempts and scientific speculation, chemists at Saarland University have achieved what many thought might be impossible: creating a long-sought silicon-based aromatic ...

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

Ball-and-stick model of a molecular complex showing three bismuth atoms forming a triangular ring between two uranium atoms, surrounded by ligand atoms including silicon, nitrogen, and carbon. By ...
