T. Yamamoto et K. Shiraishi, PREPARATION OF NEW MAIN-CHAIN-TYPE POLYQUINONES AND THEIR ELECTROCHEMICAL RESPONSE, Chemistry Letters, (9), 1998, pp. 895-896
New main chain type polyquinones, enzo[1,2-b:4,5-b']dithiophene-4,8-di
one-2,6-diyl), have been prepared by organometallic polycondensation.
In accord with a highly electron-accepting property of the monomeric u
nit, the polymer receives electrochemical reduction at a higher potent
ial than poly(anthraquinone)s.
