Formation of 2D structures and their transformation by external stimuli: a scanning tunneling microscopy study

We present a review of our recent research on the formation of two-dimensional (2D) nanopatterns via self-assembly and their transformations by external stimuli. The proper design and synthesis of functional molecules and the ability to follow their integrations on a surface would allow the effective use of their nanofunctions to produce novel nanomaterials and devices. In this context, we synthesized stimuli-responsive molecules that contain alkyl chain units, which act as not only the adsorption unit onto the substrate but also as the intermolecular interaction site. The 2D molecular arrangements were then directly visualized using scanning tunneling microscopy at the solid/liquid interface. Thermal treatment, metal coordination and ultraviolet irradiation induced chemical structural conversions of the individual molecules, which resulted in the transformations of the 2D structures.
