Their electrochemical behaviors are similar to that of TTF, so they should be good donors for conducting materials. They are novel monosubstituted asymmetric TTF-π-A donor molecules with TTF cores, which should be good donors for molecular conductors or OFET potential application.2. The tuning of the charge-transfer of TTF-PEO by solvent was realized forming the mono- and dication complexes_2CuBr_4 (5) and_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6) in the triclinic Pīand the orthorhombic Pbca space group, respectively.
