Novel CT complexes of 4-hydroxyphenylthio-substituted TTFs with TCNQ or DDQ

Novel tetrathiafulvalene (TTF) derivatives with mono-, bis- and tetrakis(4-hydroxylphenylthio) groups as hydrogen-bonding functionality, 1-3, were prepared from the lithiated TTF and a diphenyldisulfide derivative. Room-temperature resistivities of compressed pellets for 1-DDQ, 2-DDQ and 2-TCNQ were 1.1 x 10 9 , 3.8 x 10 7 and 7.8 x 10 4 Ωcm, respectively. In these complexes, alternated stacking type structures were inferred from the electronic spectra.
