Bis[oxybis(methylenethio)]tetrathiafulvalene (BOBMT-TTF) and bis[thiobis(methylenethio)]tetrathiafulvalene (BTBMT-TTF) were synthesized in two steps starting from 1,3,4,6-tetrathiapentalene-2,5-dione. The electrochemical and donor properties of both compounds are discussed. BOBMT-TTF forms a highly conducting charge transfer complex with TCNQ (σRT 10 S cm−1).

Seven new electron donors, 4,5-ethylenedioxytetrathiafulvalenes where 4′,5′-substituents are trimethylenedithio, ethylenedithio, methylenedithio, 2-oxatrimethylenedithio, methylthio, hydrogen and methyl carboxylate, are prepared, and their electrochemical properties are investigated.
molecule (EOTT), which is a new unsymmetrical TTF derivative, was synthesized, and several ion-radicalsalts of EOTT were prepared by electrochemical crystallization. Room temperature conductivities of these salts were found to be in the range of 10−1–102 S cm−1. Among them, EOTT2IBr2 and EOTT2AuI2 showed metallic behavior in electrical conduction down to ca. 15 and 4.2 K, respectively.
