1,3-Bis(1,3-dithiol-2-ylidene)-1,3-dihydrobenzo[c]heterophenes. New Fused Heteocycle-extended Donors and Their Conducting TCNQ-Complexes
摘要:
A series of new fused-heterocycle-extended donors have been synthesized by convenient and short-step reactions. Of these benzo[c]furoquinonoid-extended one has the lowest oxidation potential. TCNQ complexes of these donors exhibit fairly high conductivities even when measured on compressed pellets.

Three alkylenedithio derivatives of 1,3-bis(1,3-dithiol-2-ylidene)-1,3-dihydrobenzo[c]thiophene (BDTBT) have been synthesized. These donors exhibited an electron-donating ability near to that of tetrathiafulvalene and afforded a very stable radical cation. The powdered tetracyanoquinodimethane complex of the methylenedithio derivative exhibited a fairly high room temperature conductivity of σ = 15 Scm−1 and a semiconducting behavior with a very low activation energy of Ea = 0.050 eV.
