Multi-Tetrathiafulvalene Systems. New Donors Containing Two or Three Tetrathiafulvalene-Substituents at 1,3- and 1,3,5-Positions of Aromatic Rings

New donors having two or three tetrathiafulvalene moieties at 1,3- and 1,3,5-positions of the aromatic rings have been synthesized in order to examine the interactions of tetrathiafulvalene radical-cations in the diradical-dication or triradical-trication states. The molecular structures of two neutral donors have been determined and the conductivity of the CT complexes of the new donors have been measured.
