Abstract

Nanodevices rely on surface molecular nanostructures; they are an important issue in surface science, as well as nanotechnology research. A surface molecular self-assembly will be spontaneously formed when a drop of solution containing special molecules is deposited on a solid substrate. This self-assembly is a bottom-up strategy in nanotechnology for surface patterning. However, to realize a desirable nanocircuit, a designed and controllable molecular assembly or pattern is necessary. The desired assembly is mainly dominated by and originated from intermolecular reaction and molecule/substrate interaction. In this presentation, the recent results of the Wan Research Group on the study of surface molecular patterning will be discussed, including: The methodology for forming a molecular assembly on solid surface, the surface molecular reaction involved in the assembly, the assembly structure revealed by in situ STM, and the property of the molecular assembly.
