Formation of long-range-ordered self-assembled monolayers of dodecyl thiocyanates on Au(111) via ambient-pressure vapor deposition

The surface structure, binding condition, and reductive desorption behavior of self-assembled monolayers (SAMs) of dodecyl thiocyanate (DDTC, C12–SCN) on Au(111) formed via solution and ambient-pressure vapor depositions at 50 °C for 24 h were examined by scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV). STM imaging clearly revealed that adsorption of DDTC molecules on Au(111) in a 1 mM...
