    • Since 1H NMR spectra of MDMO-PPV and P3HT result in broad and ill-defined resonance peaks, we mimicked the processing using the model compound (E,E,E,E)-1,4-bis[(4-styryl)styryl]-2-methoxy-5-(2′-ethylhexyloxy) benzene (MEH-OPV5, which was processed under similar conditions as the MDMO-PPV cells using diethylzinc. The pristine 5-ring oligomer MEH-OPV5 (Polym. Prepr. 2000, 41, 857) contains four olefinic vinyl moieties that are clearly resolved by 1H NMR. When diethylzinc (in a toluene/THF mixture) is introduced during the processing procedure, new peaks appear between 7.84 and 7.69 ppm. Furthermore, several ill-defined multiplets arise between 3.53 and 2.41 ppm. These additional shifts are reconcilable with the formation of oxidized species such as alcohol or ketone and the complementary formation of saturated C-C bonds
