Dimer/tetramer motifs determine amphiphilic hydrazine fibril structures on graphite

Abstract: SummaryFibril structures are produced at a solvent–graphite interface by self-assembly of custom-designed symmetric and asymmetric amphiphilic benzamide derivatives bearing C10 aliphatic chains. Scanning tunnelling microscopy (STM) studies reveal geometry-dependent internal structures for the elementary fibrils of the two molecules that are distinctly different from known mesophase bulk structures. The structures are described by building-block models based on hydrogen-bonded dimer and tetramer precursors of h… Show more

“…HOPG is an ordered form of pyrolytic graphite with a high degree of crystallographic orientation of the c -axis. Polycrystalline HOPG consists of micrometer-sized grains and has been widely used as a substrate in STM studies [13] due to its high conductivity, atomic flatness and chemical inertness [4]. The surface also contains various defects such as cleavage steps, graphite strands, wrinkles/ridges, fiber-like entities, folded-over flakes, broken graphite pieces and other carbon aggregates [510].…”
