“…For both phen and bath, a two‐successive reduction wave was observed. Such a wave can be seen for some azines, and the first reduction wave may involve dimerization of the anions ,. For the N‐donor ligands, the oxidation peak currents are much smaller than the reduction ones.…”

We report the electrochemical properties, and electrogenerated chemiluminescence (ECL) of eight different organometallic complexes of Eu(III) and Tb(III), Eu(dbm)3phen, Eu(dbm)3bath, Eu(fod)3phen, Eu(tta)3phen, Tb(acac)3phen, Tb(acac)3bath, Tb(fod)3phen, and Tb(tmhd)3bpy in acetonitrile, where phen, bath, and bpy are 1, 10‐phenanthroline, bathophenanthroline, 2,2′‐bipyridyl, respectively, and the anionic ligands, acac−, dbm−, fod−, and tta− are the enolate forms of acetylacetone, dibenzoylmethanate, 6,6,7,7,8,8,8‐heptafluoro‐2,2‐dimethyl‐3,5‐octanedione, and thenoyltrifluoroacetone, respectively. The electronic states of the neutral and some charged states of the complexes were clarified with density functional theory calculations. The ECL spectra were recorded by using S2O82− as a coreactant, and for all complexes, sharp ECL spectra, which are attributable to the f‐f transitions, were observed. On the potential‐dependent ECL spectra, broad ECLs, which were originated from the ligands, were also detected. Based on the ECL behavior and the electronic states, the mechanisms of the intraconfigurational ECL were discussed.

“…Supercritical NH 3 , with its appreciable cathodic potential window [37,41], was the first SCF to be employed for the electrodeposition of silver [42]. This medium produced needle-like dendritic deposits, quite distinct from those formed in the dense liquid phase.…”

“…Even though it was unsuitable for further experiments, elemental iodine was produced at the anode in a scHCl/KI system [18]. Ammonia was also noted to have a higher dielectric and appreciable solvent properties in supercritical conditions; these investigations accomplished the anodic dissolution of silver and iron [ [9,[20][21][22][23][24][25][26]. The aim of their work was to understand the thermodynamics and kinetics of chemical reactions in SCFs, then use SCF solutions for electrosynthetic purposes [19].…”

A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte. In this review, we discuss the voltammetry obtained in these systems, studies of the double-layer capacitance, work on the electrodeposition of metals into high aspect ratio nanopores and the use of metallocenes as redox probes and standards in both supercritical carbon dioxide–acetonitrile and supercritical HFCs.
