Abstract
Methylene-, ethylene-, and propylenedithio derivatives of 1,3-bis(1,3-dithiol-2-ylidene)-1,3-dihydrobenzo[c]selenophene, MDT-, EDT-, and PDT-BDTBS have been synthesized. TCNQ complexes of MDT- and EDT-BDTBS showed fairly high conductivities and small activation energies even when measured on compressed pellets.
