Check out Franci's second Paper

This study presents dinuclear alkenylruthenium complexes featuring π-extended trans,trans-distyrylbenzene or 1,4-(2-phenylethynyl)benzene linkers, analogous to oligophenylvinylene and oligophenylethynylene oligomers, as well as the macrocyclic analogue. Characterized by NMR spectroscopy and high-resolution ESI-MS, the compounds undergo detailed examination of their electrochemical and spectroscopic properties. The study explores the efficacy of intramolecular through-bond electron transfer in…

Check out our 2023 paper on 1,4-Divinylphenylene-bridged diruthenium complexes

The study introduces four diruthenium complexes featuring divinylphenylene-bridged structures with N,O-chelating 2-hydroxypyridine and 2-hydroxy- or 8-hydroxyquinoline ligands. Through a combination of experimental techniques and (TD-)DFT calculations, the research reveals that the divinylphenylene bridge significantly influences redox processes, showcasing electron delocalization over the entire π-conjugated backbone with minimal involvement of the attached donor ligands.

Congratulations to Franci on her latest Paper

Franci's latest paper discusses PyrDPE-RuCl and PyrDPE-Ru(acac) complexes with a π-extended 2,7-di(4-phenylethynyl)pyrene linker, undergoing one-electron oxidations without displaying an intervalence charge-transfer band, suggesting a lack of electronic coupling between {Ru} entities. The electronically decoupled central pyrenyl fluorophore enables stable, red-shifted pyrene-based fluorescence emissions at 77 K, showcasing the unique electronic properties of these complexes.

Valence tautomerism involves the coexistence of redox isomers with different charge and spin density distributions, induced by intramolecular electron transfer and stimuli like light, X-ray, or temperature variations. This study proposes chromium half-sandwich complexes as alternatives, highlighting their advantages, including easily adjustable oxidation potentials, CO ligands for infrared spectroscopy, and EPR activity at a more convenient temperature (77 K) compared to ferrocene complexes.
