In organic chemistry, π-stacking systems are supramolecular structures that arise due to the dispersion force, a type of intermolecular noncovalent interaction. They are a common occurrence in nature.

Aromatic molecules consist of planar carbon-based rings with alternating single and double (π) bonds. These molecules contain 4n+2 (n = 0, 1, 2 ...) π electrons—π electrons are those involved in π ...

Whereas π-stacking systems involving aromatic compounds are quite common, those made from antiaromatic units are rare. In a recent study, researchers from Japan developed modified norcorrole molecules ...

An international research team has prepared a set of lanthanide antimony clusters that represent the first isolable compounds containing an all-metal antiaromatic ring. The achievement continues to ...

Cyclo[n]carbons have haunted University of Oxford chemistry professor Harry L. Anderson for about 30 years. His first project as a postdoctoral researcher, which he abandoned after deeming it too ...

AUSTIN, Texas – By synthesizing a stable "antiaromatic" compound, as well as a never before seen intermediate version of that compound, chemists at The University of Texas at Austin have written an ...

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 ...
