The single molecule conductance of expanded pyridinium derivative terminated by pyridyl
nitrogen as an anchoring group at both ends of the molecule in two different environments
was measured by scanning tunneling microscopy break junction technique (STM-BJ). The
values obtained in commonly used 1,3,5-trimethylbenzene (TMB) significantly differ from
the values acquired in a mixture of TMB and ethanol. Markedly lower junction length and
higher conductance indicate strong influence of adsorption of the molecule to the substrate
surface in pure TMB compared to the TMB and ethanol mixture.
