Properties of SAMs and Gold-Nanoparticle of Oligothiophene which can Control Intermolecular Interaction

Abstract

Previously, we succeeded in stabilization of oligothiophene radical cations and steric control of intermolecular interaction by the use of annelation with bicyclo[2.2.2]octene. In this work, we synthesized oligothiophene which has thiol to be bonded with gold and bicyclooctene units to control intermolecular interaction. We have investigated SAMs on gold and gold-nanoparticles with those oligothiophenes and will report these results.
