One electron oxidation of 4-(2-tetrathiafulvalenyl)phenyl substituted dicyanomethylides (1-) gave black solids of the title radicals (1(.)). They exhibit quite high electrochemical amphotericity, which may be responsible for their good electrical conductivities (sigma = ca. 10(-7) S cm(-1)) as a single component. Isomeric radicals (2(.)) with a m-phenylene spacer could not be obtained under the similar conditions probably due to insufficient delocalization of the unpaired electron.
