چکیده انگلیسی
The chiral polyoxometalate [H4Co2Mo10O38]6â has been used in the preparation of hybrid materials in the form of crystals or polymeric films. A new radical salt of the donor bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF or ET) containing the two enantiomers of this polyoxometalate has been obtained by electrocrystallization. This radical salt shows semiconducting behavior with room temperature conductivity of 9Â S.cmâ1 and activation energy of 40Â meV. Polypyrrole films doped with a racemic mixture of polyoxometalates and also the enantiomerically pure (+)589-[H4Co2Mo10O38]6â have been prepared electrochemically. Circular dichroism experiments suggest that the chiral polyoxometalates do not induce macroasymmetry into the polypyrrole chains during polymerization. Conductivities at room temperature of these polymer films range between 36 and 49Â S.cmâ1.
