Hydrophobicity and CH/π-interaction-driven self-assembly of amphiphilic aromatic hydrocarbons into nanosheets.

The hydrophobicity and CH/π-interaction-driven self-assembly of an amphiphile that contains a biphenylanthracene group furnishes two-dimensional aggregates in dilute aqueous solution. A windmill-shaped molecular packing structure that arises from multiple intermolecular CH/π interactions of the aromatic hydrocarbons is the key motif for the self-assembly into micrometer-scale nanosheets.
