The synthesis of novelunsymmetrically substituted TTFs and the subsequent transformation into a donor-σ-acceptor system is reported; The CV and the spectroelectrochemical studies reveal the presence of both electroactive moieties.
unsymmetrically substituted TTF derivatives as precursor for the preparation of novel TTF-based donor-bridge-acceptor dyads is reported. Substitution on the acceptor p-benzoquinone moiety has a strong influence on the reduction potentials in compounds 18 which, however, do not show the presence of a charge transfer band in the electronic spectra. The cyclic voltammetry measurements reveal two oxidation waves
Several derivatives of title donors (1a-c) have been synthesized. The cyclic voltammogram of tetrakis(hexylthio) derivative 1c exhibited three pairs of double-electron transfer waves. The iodine complexes of 1a-c showed relatively high conductivities of 10−1 - 101 S cm−1 at room temperature.
