title: Conductive poly(2,5-substituted aniline)s highly soluble both in water and organic solvents.
abstract: Highly soluble conductive polyanilines were synthesized from newly designed aniline derivatives: 2,5-bis(2-methoxyethoxy)aniline (2) and 2,5-bis[2-(2-methoxyethoxy)ethoxy]aniline (3). The corresponding polyanilines, P2 and P3, were characterized by means of fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), and UV-VIS-NIR spectroscopies. The electrical conductivities at room temperature of emeraldine salt forms of P2 (P2-ES) and P3 (P3-ES) were evaluated to be sigma(rt) = 2.4 x 10(-3) and 1.7 x 10(-3) S/cm, respectively. The length of ethylene-1,2-dioxy chains on the polyaniline scarcely affected the electronic conductivity. A simple modification at 2,5-positions of aniline by introducing 1,2-ethlenedioxy groups dramatically altered the solubility of polyanilines in common organic solvents and water (400 g/L for P3-ES).
