How the Anchoring Site on Two Extended Tetrathiafulvalenes Impacts the Electronic Communication through a Bis(acetylide)ruthenium Linker

Abstract : The interplay between two extended tetrathiafulvalenes connected, from either the dithiole rings or the anthraquinodimethane moieties, through a bis(acetylide) ruthenium linker has been studied within the novel complexes trans-[Ru(C CDTTFAQ)(2)(dppe)(2)] and trans-[Ru(C CATTFAQ)(2)(dppe)(2)]. Cyclic voltammetry and spectroelectrochemical investigations show that the organic and inorganic electrophores are electronically coupled within these complexes. Moreover, the electronic. communication between the two organic electrophores depends on the localization of the anchoring site of the organometallic bis(acetylide) ruthenium linker on the organic electrophores.
