M. Iwamatsu et al., Synthesis and electrical conducting properties of unsymmetrical spiro compounds bearing a tetrathiafulvalenyl group, SYNTH METAL, 102(1-3), 1999, pp. 1617-1618
In expectation of a first single-component organic metal, several spiro com
pounds bearing each of tetrathiafulvalenyl and benzo groups were now synthe
sized, one of which exhibited high room-temperature electrical conductivity
(sigma(n) ,ca. 10(-3) S.cm(-1)) on the compressed pellet.
