Tuning the Electrical and Optical Properties of Dinuclear Ruthenium Complexes for Near Infrared Optical Sensing

Redox-active dinuclear ruthenium complexes with various 1,2-dicarbonylhydrazido (DCH) ligands are designed and prepared to have intense absorption in the near-infrared region for potential optical sensing in aqueous media, as demonstrated for sensing hydrogen peroxide in this study.
