Abstract

Self-assembly of melem on Ag(111) as studied by Scanning-Tunneling-Microscopy (STM) in ultra-high vacuum revealed a great structural variety. In total, five porous and two densely packed monolayer polymorphs were observed. All structures are stabilized by intermolecular hydrogen bonds, where melem–melem arrangements are based on very few basic motifs. Six out of seven polymorphs can be described by a unified concept.

Abstract

Interfacial self-assembly of specific monolayer structures from solution on a graphite surface can be steered by tuning the interplay between solute–solute and solute–solvent interactions. [ABSTRACT FROM AUTHOR]
