Formazans (Ar1-NH-NCR3-NN-Ar5), a class of nitrogen-rich and highly colored compounds,
have been known since the late 1800s and studied more closely since the early 1940s …

Controlled ligand‐based redox‐activity and chemical non‐innocence are rapidly gaining
importance for selective (catalytic) processes. This Concept aims to provide an overview of …

While β-diketiminate (BDI or 'nacnac') ligands have been widely adopted to stabilize a wide
range of metal ions in multiple oxidation states and coordination numbers, in several …

Bis (formazanate) iron (II) complexes undergo a thermally induced S= 0 to S= 2 spin
transition in solution. Here we present a study of how steric effects and π-stacking …

The effect of extended π conjugation on the spectroscopic and electrochemical properties of
boron difluoride (BF2) formazanate complexes was studied by the systematic comparison of …

Redox-switching of a formazanate zinc catalyst in ring-opening polymerization (ROP) of
lactide is described. Using a redox-active ligand bound to an inert metal ion (Zn2+) allows …

Electrochemiluminescence (ECL) of a boron difluoride formazanate dye was investigated in
the presence of tri-n-propylamine as a reductive co-reactant. The ECL mechanism was …

Abstract Evaluation of three subclasses of boron difluoride formazanate complexes bearing
o‐, m‐, and p‐anisole N‐aryl substituents (Ar) as readily accessible alternatives to boron …

The synthesis of a series of (formazanate) boron difluorides and their 1-electron reduction
products is described. The neutral compounds are fluorescent with large Stokes shifts. DFT …

Spin-crossover in a pseudo-tetrahedral bis (formazanate) iron (II) complex (1) is described.
Structural, magnetic, and spectroscopic analyses indicate that this compound undergoes …
