摘要：

The nature of polyaniline (2A or 2S form) dissolved in concentrated sulfuric and methanesulfonic acid has been investigated by (UV-Vis-NIR) optical absorption and Raman scattering using various exciting laser lines. Two different polaronic species have been evidenced and selectively analysed, using N-15 labelled and perdeuterated ring derivatives. Addition of water induces formation of 2S-like materials, probably forming a sol and not a true solution. The achievement of the metallic state seems to be related to the ordering of the chains intercalated with water, oxonium ions and anions.
