Abstract:

Molecular self-assembly [1,2] is one of the most promising strategy for giving surface specific properties with a nanoscale control. An important field of application of self-assembled monolayers (SAMs) [2] is the so-called “molecular electronics” within which self-assembly is a very powerful way to obtain the organization at large surface scale of molecules showing particular electro-optical properties.
After the principle of SAM preparation, the motivation of developing SAMs of small organic molecules will be illustrated by some examples of controlling the molecular structuration on silicon surfaces [3, 4]. How organization at the molecular scale acts on electro-optical properties of molecular chromophores will then be discussed through two examples: a structure-electrical properties relationship probed by STM [5] and the SAM of a novel push-pull thiophene-based chromophore [6].
