The concept of aromaticity underpins much of modern organic chemistry, describing the unusual stability and reactivity of cyclic molecules whose π-electrons are delocalised over a planar framework.

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 ...

In 1862, a chemist nodded off in front of a fire and began to dream. August Kekulé had been pondering the most pressing question in his field at the time: what was the chemical structure of a curious ...
