New extended donors, 2,2'-(2,5-dihydrothiophene-2,5-diylidene)bis(1,3-benzodithiole) and its di- and tetra-methyl derivatives having a chalcogen atom and four additional sp2 carbons at the central part of dibenzotetrathiafulvalene (DBTTF) molecule have been synthesized.The electrochemical properties and conductivities of their complexes have been demonstrated characterizing a good coplanar conformation in the oxidized states.
