Assembly of a Nanoscale Chiral Ball through Supramolecular Aggregation of Bowl-Shaped Triangular Helicates

Bowls to balls: Triangular bowl‐shaped copper(I) circular helicates based on pyridylimine ligands are assembled by mixing readily available reagents. The bowl‐shaped topography of the triangles controls the supramolecular aggregation of four of these units into a chiral tetrameric ball‐shaped struct...

Zusammenfassung:Bowls to balls: Triangular bowl‐shaped copper(I) circular helicates based on pyridylimine ligands are assembled by mixing readily available reagents. The bowl‐shaped topography of the triangles controls the supramolecular aggregation of four of these units into a chiral tetrameric ball‐shaped structure (see picture) held together by face–edge (CH⋅⋅⋅π) π interactions and CH⋅⋅⋅F interactions.
