“…[Ln(tta) 3 ]⋅2 H 2 O,19 tributylstannyltetrathiafulvalene,20 tetrathiafulvaleneamido‐2‐pyridine‐ N ‐oxide ligand (L 2 ) and complex 3 were prepared according to the literature procedure 11e…”

Tetrathiafulvalene-based group XV ligands: Synthesis, coordination chemistry and radical cation salts

“…Reactivity of the different halogenated pyridines in this Stille palladium-catalyzed condensation is, as expected, in the order Py-I > Py-Br Py-Cl. This chemical approach has been successfully developed for the synthesis of mono and bis-pyridyl-TTFs (Scheme 4) [13][14][15] and was also extended to the synthesis of 3-quinolyl and 3,5-pyrimidyl [13] derivatives 10 and 11. The mono and bis-pyridyl-TTFs can also be prepared from the unsymmetrical or symmetrical coupling using the 4-pyridyl-1,3-dithiole-2-one in the presence of neat triethylphosphite but in rather low yields [16][17][18].…”

“…The mono and bis-pyridyl-TTFs can also be prepared from the unsymmetrical or symmetrical coupling using the 4-pyridyl-1,3-dithiole-2-one in the presence of neat triethylphosphite but in rather low yields [16][17][18]. The pyridine substituent directly linked to the donor core has no significant electron withdrawing effect on the redox properties of the donor core as the oxidation potentials remain very close to those of the non-substituted TTFs [10][11][12][13][14][15][16][17] (Table 1).…”

Effect of light irradiation on the gas sensor characteristics of the SnO2 and ZnO modified by tetrathiafulvalene derivative

“…During the last decade, a particular attention has been devoted to the design of TTF donors involving a π-extended system [19,20] known to stabilize the metallic state [19,21]. Thus, TTF derivatives incorporating aromatic substituents [22,23] and dimeric TTFs linked by different aromatic conjugated spacers [24,25] were successfully used to form highly conducting solids [26,27].…”
