Nine new heterocyclic {pi}-electron donors 10a-c, 11a-c, and 12a-c based upon the well-known TTF (tetrathiafulvalene) system, but incorporating a pyrrole, thiophene, or furan ring between the 1,3-thiole rings, have been synthesized. The compounds show two single-electron reversible oxidation waves in cyclic voltammetry. Some TCNQ complexes and conductivity measurements are reported, indicating the new compounds to be good candidates for {open_quotes}organic metals{close_quotes}. The influence of the central conjugated system on redox properties is discussed using MNDO-PM3 calculations. 17 refs., 5 figs., 1 tab.
