Synthesis and photophysical properties of multi-Ru2+ terpyridine complexes: from di-nuclear linear to star-shaped hexa-nuclear architectures†
Abstract
A series of terpyridine based Ru2+ complexes G1, G2, G3, and G4 were designed and synthesized, the solubility of complexes was enhanced by introducing a multiple tailed long aliphatic chain; full characterization has been performed with 1H NMR, 13C NMR, ESI-MS and UV-vis measurements. Electrochemical behaviours of these complexes have been investigated.
