STM observation of 12-hydroxyoctadecanoic acid and its 4,4′-bipyridinium salt self-assembled on a graphite surface†

Abstract

Self-assembled monolayers of the gelling agent, 12-hydroxyoctadecanoic acid and its 4,4′-bipyridinium salt have been observed on the solution graphite interface using scanning tunnelling microscopy (STM) and the molecular patterns are discussed wth respect to the intermolecular hydrogen bond network.
