Supramolecular nanopatterns of H-shaped molecules†
Abstract
Alkoxy-substituted phenylene–ethynylene–butadiynylenes (PEBs) are connected via 1H-benzimidazole units to form H-shaped molecular scaffolds that self-assemble on graphite at the solid/liquid interface. Spacer lengths and end groups determine supramolecular tiling patterns, as shown via scanning tunneling microscopy (STM).
