In 1825 Michael Faraday isolated a sweet-smelling chemical that he dubbed bi-carburet of hydrogen. That molecule, better known as benzene, is perhaps the most famous molecular ring in chemistry.

Aryl (benzene ring) compound having unpaired electrons. *3) Photocatalyst A catalyst that can perform electron or energy transfer by absorbing light (here, visible light). *4) Organic catalyst ...

A huge molecular wheel has set a new record as the largest aromatic ring (Nat. Chem. 2020, DOI: 10.1038/s41557-019-0398-3). The molecule could be a step toward making even bigger rings that serve ...
