Grafting of Organoruthenium Oligomers on Quartz Substrates:  Synthesis, Electrochemistry, Optical Properties, and AFM Investigations

Abstract

A new type of organometallic oligomers has been obtained from the reaction of [(C6Me6)2Ru2H3]+ and dithiophenol derivatives. These oligomers are highly ordered because of the steric hindrance around the metal center and the rigidity of the aromatic units. The electrochemical behavior of the monomers and the oligomers has been studied both in reduction and in oxidation modes. The oligomers have been grafted via electrostatic interactions on glass substrates prefunctionalized by self-assembled monolayers (SAMs). The optical properties of the films have also been investigated.

Charge and spin transport in single and packed ruthenium-terpyridine molecular devices: Insight from first-principles calculations

“…Numerous experimental investigations, accompanied by theoretical approaches 6 , were conducted in the search for possible molecular building blocks for future devices with tunable magnetic behaviour 7 8 9 10 11 12 . Seminal device fabrication-driven searches have been directed to the study of ordered thin films, from multilayers to monolayer assemblies 13 14 15 16 17 18 19 20 , and addressed the behaviour of single molecules on metallic surfaces 21 22 23 24 25 26 .…”
