| Research Abstract |
In order to create the compounds which have both conductivity and ferromagnetic properties, we designed the donor systems bearing TTF- or ferrocene-unit at the 1,3-or 1,3,5-positions of aromatic rings. The donor molecules with TTF-units have been synthesized using the palladium-catalyzed cross-coupling reaction of tetrathiafulvalenyltin with halogenated benzene derivatives. The dication diradicals and trication triradicals prepared from the TTF-donors show conductivity like a semi-conductor. However, these radical salts indicate almost no ferromagnetic interaction between radical centers. The donor molecules with ferrocene-units have been synthesized by the palladium-catalyzed cross-coupling reaction of ferrocenylzinc reagent with halogenated benzene derivatives. This reaction easily produces the products in a one-pot procedure. The dication diradical or trication triradical salts of the ferrocenedonor show some interaction of ferrocenyl irons. However, the conductivity measurements of this system indicate that the radical salts are a insulator.
