The Formazanate Ligand as an Electron Reservoir: Bis(Formazanate) Zinc Complexes Isolated in Three Redox States [PDF]
Angewandte Chemie International Edition, 2014 The synthesis of bis(formazanate) zinc complexes is described. These complexes have well-behaved redox-chemistry, with the ligands functioning as a reversible electron reservoir. This allows the synthesis of bis(formazanate) zinc compounds in three redox

Near‐Infrared Boron Difluoride Formazanate Dyes
Chemistry – A European Journal, 2021 AbstractNear‐infrared (NIR) dyes are sought after for their utility in light harvesting, bioimaging, and light‐mediated therapies. Since long‐wavelength photoluminescence typically involves extensive π‐conjugated systems of double bonds and aromatic rings, it is often assumed that NIR dyes have to be large molecules that require complex syntheses.
