“…It has been reported that the two anodic waves appeared in dimethyl sulfoxide when acac ¹ was liberated from the iron complex during the reduction process of Fe(acac) 3 . 23 However, only one anodic peak was observed in BMPTFSA, implying that [Fe(acac) 3 6 ] 3¹/4¹ and more negative than those of other iron complexes. It is known that the higher donor property, namely Lewis basicity, of the ligands leads to the stronger interaction between the metal ion and ligand, resulting in the negative shift of the redox potential.…”

“…14,15,22,26 The D value of Fe(acac) 3 in BMPTFSA was much smaller than those in acetonitrile, reflecting the higher viscosity (73 mPa s) of BMPTFSA containing 10 mM Fe(acac) 3 . As abovementioned, the negative redox potentials of [Fe(CN) 6 ] 3¹ and Fe(acac) 3 are considered suitable for the anolyte of the redox flow batteries. The D value of Fe(acac) 3 was larger than that of [Fe(CN) 6 ] 3¹ (0.6 © 10 ¹7 cm 2 s…”

“…) in BMPTFSA, probably because the electrostatic drag in addition to the viscous drag needs to be taken into account for the highly charged complex of [Fe(CN) 6 ] 3¹ . 8 The high diffusivity of Fe(acac) 3 is expected to be beneficial for the redox battery performance.…”

“…Aprotic ionic liquids are potential electrolytes to these applications in terms of the attractive features including negligible vapor pressure, wide electrochemical window and intrinsic ionic conductivity, offering enhanced thermal stability and large cell voltage. [1][2][3][4][5][6][7][8][9] Among a variety of aprotic ionic liquids, bis(trifluoromethylsulfonyl)amide (TFSA ¹ ) based ionic liquids are favorable electrolytes for the metal complexes since the donor ability of TFSA ¹ -based ionic liquids is weak as compared with conventional solvents, resulting in stable formation of metal complexes without liberation of the ligands. 4 One of the typical redox couples is Fe(III)/Fe(II).…”

The redox reaction of tris(acetylacetonato)iron(III) (Fe(acac) 3 ) on a glassy carbon electrode was investigated in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA). A one-electron transfer redox reaction of [Fe(acac) 3 ] 0/− showed the relatively negative potential of −1.4 V vs. Ag|Ag(I). The diffusion coefficient of Fe(acac) 3 estimated by chronoamperometry was (1.4 + 0.1) × 10 −7 cm 2 s −1 . The redox properties examined in this study suggested that the redox reaction of [Fe(acac) 3 ] 0/− can be utilized in the negative half-cell reaction of redox flow batteries.
