Tris(tropolonato) ruthenium as a hub for connecting π-conjugated systems

In this study, the intramolecular electronic communication between π-conjugated moieties bridged by the tris-chelate [Ru(trop)₃] (trop = tropolonate) framework has been investigated and compared with [Ru(acac)₃] (acac = acetylacetonate) derivatives.
