文摘
The molecular structure of submonolayer-coverage phases of 3-(thioacetyl)-propanoylferrocene and 5-ferrocenylpentanethiol in mixed layers with alkanethiols on Au(111) was resolved by scanning tunneling microscopy. Theferrocenes formed a striped surface phase, similar to the lying-down structures of alkanethiols, resulting in equallyspaced rows of the ferrocene moieties. The obtained nanoscale lattice of functional groups on the surface offers aninteresting potential for the patterning of small, periodic structures with precise distance control via a hydrocarbonspacer.
