A series of 1, 1'-dithiolate ligands were used in the attempted prepara­tion of metal complexes. These bidentate sulphur ligands were subsequently used in aromatic nucleophilic substitution reactions giving rise to several novel organic donor molecules. The electrochemistry data of two of the donors and their subsequent use in the preparation of donor-acceptor com­pounds is presented. One donor-acceptor compound exhibited high room temperature conductivity (up to 900 S cm^{-1}) and remained metallic down to low temperature. One donor containing two tetrathiafulvalene units was studied by near infrared absorption spectroscopy. An intervalence transition in the monocation form of this donor was observed, indicating that it behaves as a class II mixed valence compound.
