Adlayers and Low-Dimensional Assemblies of a TTF Derivative at a Liquid−Solid Interface

Scanning tunneling microscopy has been employed to investigate the ordering of a tetrathiafulvalene derivative at a liquid−solid interface at room temperature. Surprisingly, in addition to the observation of polymorphous two-dimensional pseudocrystals, lower-dimensional assemblies are observed. Scan...

Description
Summary:Scanning tunneling microscopy has been employed to investigate the ordering of a tetrathiafulvalene derivative at a liquid−solid interface at room temperature. Surprisingly, in addition to the observation of polymorphous two-dimensional pseudocrystals, lower-dimensional assemblies are observed. Scanning tunneling spectroscopy at the individual molecule level reveals rectifying behavior, independent of the molecular ordering.
