Two types of linear oligomers, namely Ph/NH2 and NH(2)lNH(2) end-capped oligoanilines have been synthesized by SNAr coupling/reduction sequence. The H-1 NMR spectra of obtained compounds are strongly influenced by electron withdrawing or electron donating effects of the terminal groups (NO2 or NH2, respectively). The UV-Vis spectra of nitroamines exhibit two peaks characteristic for two types of the phenylene substituents (-NH- or NO2), whereas UV-Vis spectra of oligoanilines show only one peak attributed to the Pi-Pi* transition in the phenylene rings. The oxidation of oligoanilines was also followed by UV-Vis spectroscopy.
