The syntheses of eight derivatives of BEDT-TTF (ET) containing pyridine, 2,2′-bipyridine or 2,4′-pyridylpyrimidine binding sites on a side chain are reported, for use in the preparation of organic/inorganic hybrid materials. The intermediate hydroxyethyl derivative of BEDT-TTF is prepared in an efficient five-step procedure.

Preparation and characterization of a new organic donor molecule bis(hydroxymethylethylenedithio)-tetrathiafulvalene is reported. Cyclic voltammogram (Figure 1) of the donor molecule shows two reversible redox processes in n-Bu4NBF4/DMF system at half-wave potentials of 0.64 and 0.81 V vs SCE, respectively, which are higher than those of the well-known organic donor molecule bis(ethylenedithio)-tetrathiafulvalene with the corresponding values of 0.60 and 0.73 V , respectively. In addition, the π-donor ability of some related donor molecules of the same series is compared and the effects of solvents on the half-wave potentials of the donors are studied.
Synthesis of some functionalised isomeric bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) and dithiophenetetrathiafulvalene (DTTTF) π-Donors

The synthesis of some functionalised, isomeric, symmetrical tetrathiafulvalene derivatives containing 4,5-(ethylenedithio)-1,3-dithiole and 4,5-(propylenedithio)-1,3-dithiole units is described. These contain hydroxy, chloro and cyano functionalities (4, 6, 9 and 12). Interestingly, attempted coupling of 4,5-bis(propargythio)-1,3-dihiole-2-thione 13, to obtain the corresponding TTF, 14 afforded the novel thione, 5-methylthieno[2,3-d]-1,3 dithiole-2-thione 15. Self coupling of thione 15 in the presence of trimethyl phosphite afforded new functionalised dithiophenetetrathiofulvalenic 16. The X-ray crysal structures of 4,5-bis(propargyldithio)-1,3-dithiole-2-thione 13 and 5-methylthieno[2,3-d]-1,3-dithiole-2-thione 15 are described.

The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups is achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and efficient
Syntheses of new electron donors with hydroxymethyl groups and studies on their cation-radical salts

New electron donors 4,5-ethylenedithio-4',5'-(1-hydroxypropane-2,3-diyldithio)tetrathiafulvalene (1a), 4,5-bis(methylthio)-4',5'-(1-hydroxypropane-2,3-diyldithio)tetrathiafulvalene (1b), 4,5-ethylenedithio-4',5'-(1,4-dihydroxybutane-2,3-diyldithio)tetrathiafulvale ne (1c) and 4,5-bis(methylthio)-4',5'-(1,4-dihydroxybutane-2,3-diyldithio)tetrathiafulval ene (1d) with hydroxymethyl groups were synthesized and characterized spectroscopically. Their redox potentials were determined using cyclic voltammetry. Crystals of cation-radical salts based on these new electron donors, (1a)2·ClO4, (1c)2·Cl, (1c)2·I, were obtained by standard electrochemical methods. The crystal structure of (1c)2·Cl was determined and studied. Electrical measurements of the cation-radical salts indicated that they displayed semiconducting behaviors, however, with good conductivities at room temperature: 0.68 S cm-1 for (1a)2·ClO4 and 0.10 S cm-1 for (1c)2·Cl.
