A facile synthesis and characterization of semiconducting p-phenylenediamine-aniline copolymer

Synthesis of p-phenylenediamine (p-PDA)-aniline copolymer was carried out using K2S2O8 and (NH4)(2)S2O8 as an oxidizing agent. Of the two, K2S2O8 was found to be the best oxidizing agent and the newly synthesized copolymer was characterized by UV-visible, FT-IR, fluorescence, proton NMR, cyclic voltammetry, solubility and SEM studies. Conductivity studies of the same with different dopants were also made and found to fall in the region of semiconductor. Morphological study revealed that the neutral copolymer forms into less regular and amorphous structure. (C) 2010 Elsevier B.V. All rights reserved.
