Light-induced structural transformation in self-assembled monolayer of 4-(amyloxy) cinnamic acid investigated with scanning tunneling microscopy
Article Abstract:
Electrochemical scanning tunneling microscopy (ECSTM), cyclic voltammetry and infrared (IR) spectroscopy were used for examining the effect of ultraviolet (UV) irradiation on the structural transformation in a self-assembled monolayer of 4-(amyloxy)-cinnamic acid (AOCA) on Au (111). A new adlayer with different molecular arrangement and a symmetry of (5*8) is observed after UV-light irradiation onto the adlayer.

Molecular architecture of oligothiophene on a highly oriented pyrolytic graphite surface by employing hydrogen bondings
Article Abstract:
A series of oligothiophenes with carboxylic groups and alkane chains are synthesized to achieve a controllable and predictable molecular architecture on a two-dimensional (2D) surface. The analysis has shown that the hydrogen bonding plays an essential role in the formation of the ordered assemblies and a controlled 2D molecular assembly is fabricated by using hydrogen bondings.

Time-dependent organization and wettability of decanethiol self-assembled monolayer on Au(111) investigated with STM
Article Abstract:
A study on the time-dependent organization of a decanethiol self-assembled monolayer (SAM) at a designed solution concentration onto a Au(111) surface is performed with scanning tunneling microscopy (STM). The results revealed that the formation process and structure of decanethiol SAMs were well related to sample preparation conditions.
