What is it about?

Intramolecular folding indicated by C-H-pi interaction in solution by NMR further confirmed in solid by X-ray crystallography due to intramolecular pi-pi interaction.

Why is it important?

To the best of our knowledge, this is the first example of a folded compound due to intramolecular arene interaction in the solid state.

Perspectives

Further studies will confirm the utility of intramolecular pi-pi interaction for control in conformation.
