A water-soluble derivative of tetrathiafulvalene exhibiting pH sensitive redox properties

Metal Co(II) and Ni(II) coordination compounds with tetrathiafulvalene carboxylate

“…The results can be assigned as the two-step one-electron oxidations, TTF + /TTF and TTF 2+ /TTF + , since the redox properties of TTF derivatives have been well characterized. Comparing with the data of 1 (0.280 and 0.556 V) measured in H 2 O-CH 3 CN (1:1 v/v) [18], a positive potential shift of the data was observed. The result is reasonable, since the redox active species is a dicarboxylate anion, which is more stable in higher polar solvent and hydrogen bonding solvent in redox view.…”

“…The result is reasonable, since the redox active species is a dicarboxylate anion, which is more stable in higher polar solvent and hydrogen bonding solvent in redox view. Because of the partial hydrolyzation of 1, a new peak ðE 0 ox ð1ÞÞ appears at 0.70 V in the first redox process, that is the oxidation of the protonated salt, HL À to HL [18]. In the second redox process, only one pair of peak appeared.…”

“…The TTF unit takes a boat configuration with dihedral angle ca. 25°and 20°, respectively [18], which is a common character found for neutral TTF compounds. All these characters in structure mean that the molecule is a r donor-acceptor system.…”

Slow Magnetic Relaxation in Unprecedented Mono-Dimensional Coordination Polymer of Ytterbium Involving Tetrathiafulvalene-Dicarboxylate Linker

“…The precursor Yb(hfac) 3¨2 H 2 O (hfac´= 1,1,1,5,5,5-hexafluoroacetylacetonate anion) and the ligand Na 2 L were synthesized following previously reported methods [34,35]. All other reagents were commercially available and used without further purification.…”

Magnetic and Photo-Physical Properties of Lanthanide Dinuclear Complexes Involving the 4,5-Bis(2-Pyridyl-N-Oxidemethylthio)-4′,5′-Dicarboxylic Acid-Tetrathiafulvalene-, Dimethyl Ester Ligand

“…These ester moieties could also be hydrolysed into carboxylate functions acting as additional coordinating sites [60].…”
