A New Superlattice of Cyclohexanethiol Self-assembled Monolayers on Au(111) Formed at a Low Solution Temperature
High-resolution scanning tunneling microscopy (STM) imaging revealed that cyclohexanethiols (CHTs) on Au(111) form high-density self-assembled monolayers (SAMs) with a (5 × 2√3)R35° superlattice at a low solution temperature of −20 °C. This packing structure is comparable to a (5 × 2√10)R48° superlattice formed at room temperature. From this result, it was found that the two-dimensional structure of CHT SAMs on Au(111) was strongly influenced by the solution temperature, unlike alkanethiol SAMs.
