Title: Self-Assembly of Gold Nanoparticles into 2D Arrays Induced by Bolaamphiphilic Ligands
Abstract: We performed synthesis and investigated the self-assembly properties of nanoparticles (NPs) with covalently attached bolaamphiphilic (B-AuNPs). The judiciously designed coating rendered the NPs and induced their self-assembly. The B-AuNPs formed ordered structures over large areas upon simple drop-casting. films exhibited an uncommon and applicable topography, consisting of packed rings of inner diameter of around 30 nm, with the B-AuNPs the rim and an empty interior. We introduced and proved an explanation of how the structures were formed. The involved elements of geometric packing and ligand reorganization. contact with the hydrophilic surface, ligands rearranged at the of the metallic cores of the B-AuNPs so that the bolaamphiphilic (constituting ca. 50\% of the coating) were in proximity to the while the hexanethiol moieties moved away from it. The mechanism is of general relevance for the design of functional NPs capable of self-assembly.
