Abstract:
Repeated nucleophilic aromatic substitutions (SNAr) were used to synthesize the
donor-acceptor conjugated polymer consisting of alternated electron poor thiophene and
electron rich phenylenediamine units. Polymer A was obtained from SNAr reactions of 2,5-
dichloro-3,4-dinitrothiophene (DCDNT) and p-phenylenediamine as red-brown, partially
soluble solid. Its characterization by IR indicated the presence of both amino (3350 cm-1; NH
st) and nitro groups (1544,1331 cm-1). 1H-NMR of the DMSO-soluble solid showed broad
signals of aromatic protons at 6.8-7.8 ppm. The polymer was then reduced with SnCl2 to
obtain all electron-rich polymer B, in which its IR spectrum no longer showed the signals of
nitro groups but still showed the broad aromatic protons signals at 6.0-7.5 ppm. To improve
the solubility, the black solid Polymer C was similarly prepared through SNAr process from
DCDNT and N,N-di-sec-butylphenylenediamine. Its characterization by IR indicated the
presence of nitro groups (1605,1376 cm-1). 1H-NMR of the CDCl3-soluble solid showed
broad signals of aromatic protons at 6.74-6.99 ppm, and alkyl groups at 0.19-2.37 ppm. The
polymer was then reduced with SnCl2 to obtain all electron-rich polymer D, in which its IR
spectrum exhibited no signal of nitro group. Its 1H-NMR of the DMSO-soluble portion
showed the broad aromatic protons signals at 6.0-7.7 ppm and alkyl groups at 0.7-1.7 ppm
