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 ...

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 ...

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 ...

Polycyclic aromatic compounds, characterised by fused aromatic rings, underpin advances in organic electronics, photonics and catalysis. Synthetic approaches broadly divide into bottom-up ...

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 ...

Pyridines, molecules consisting of one nitrogen and five carbons in a six-membered aromatic ring, are an important chemical stepping stone for a variety of drugs, agricultural products, and materials.

Electrochemical reactions for synthesis of organic compounds would find wider applications if they were independent of power supply. Now, researchers have exploited the flow of electrolytes in an ...

Discovery of seven-ring cyanocoronene in a star-forming cloud challenges assumptions about the abundance and formation of complex organic molecules in the universe. (Nanowerk News) A team of chemists ...
