K. Takahashi et S. Tarutani, NOVEL ELECTRON-ACCEPTORS FOR ORGANIC CONDUCTORS - [2-(DICYANOMETHYLENE)-2,5-THIENOQUINO]CYCLOPROPANE DERIVATIVES, Journal of the Chemical Society, Chemical Communications, (4), 1994, pp. 519-520
The title [3]radialene derivatives, having a hybrid structure of 2,5-b
is(dicyanomethylene)-2,5-dihydrothiophene (thiophene-TCNQ) and tris(p-
benzoquino)cyclopropane, and giving a stable radical anion and a diani
on on two-step one-electron reductions, have been efficiently synthesi
sed and the electrical properties of the conductive charge-transfer co
mplexes with tetrathiafulvalene and related donors are described.
