| Abstract: | The emeraldine base of poly(o-toluidine) and N,N′-bis(4′-dimethylaminophenyl)-1,4-quinonediimine were demonstrated to undergo oxidative complexation to VCl3, affording the corresponding conjugated complexes. The complexation proceeds via reduction of the quinonediimine moiety with oxidation of V(III)–V(IV), in which the vanadium species is considered to play an important role in both the complexation and reduction. |
