Tetrathiafulvalene derivatives (TTF1-TTF9) bearing fluorinated Ph groups attached through the sulfur bridges have been synthesized by employing a copper-mediated C-S coupling reaction of C6H5-xFxI (x = 1, 2, 5) and a zinc-thiolate complex, (TBA)2[Zn(DMIT)2] (TBA = tetra-Bu ammonium, DMIT = 1,3-dithiole-2-thione-4,5-dithiolate), as the key step. Particularly, the selective synthesis of C6F5-substituted (TTF8) and C6F4-fused (TTF9) TTFs from C6F5I is disclosed. The physicochem. properties and crystal structures of these TTFs are fully investigated by UV/Vis absorption spectra, cyclic voltammetry, MO calculation, and single-crystal X-ray diffraction. The exchange of hydrogen vs. fluorine on the peripheral Ph groups show a notable influence on both the electronic and crystallog. natures of the resulting TTFs: (1) lowering both the HOMO and the LUMO energy levels, (2) modulating the electrochem. properties by regioselective and/or the degree of fluorination, (3) enhancing the driving forces of stacking by multiple fluorine interactions (F···S, C-F···π/πF, C-F···F-C, and C-F···H). This work indicates that the decoration with fluorinated phenyls holds promise to produce functional TTFs with novel electronic and aggregation features.
