Scanning Probe Microscopy Studies of the Patterned Self-Assembled Monolayer Surfaces on Gold

摘要

The self-assembly of alkanethiols deposited on the gold surface can give rise to versatile functionalities to the surfaces. We have prepared alkanethiols containing pyridine moiety, Py-CH_2(CH_2)_(10)SH, to provide ligand functionality to the surface, μ-contact printing (μ-CP) method has been applied to pattern the adsorption of modified alkanethiolates on the surface of gold on a submicron scale (FIGURE 1). With this printing, organic surfaces patterned with well-defined regions exhibiting different chemical and physical properties have been produced. Au-coated mica substrates were treated with functionalized thiols to produce self-assembled monolayer (SAM) surfaces.
