Abstract : The synthesis of well characterized polyaniline oligomers H-(C6H4)-N(H)n-H (n=4, 8, 16) (depicted for simplicity in the fully reduced form) from commercial dianiline, (n=2) is reported. Rapid oxidative coupling reactions result predominately in the formation of tetramer, octamer and hexadecamer, respectively, when the reagents are mixed in optimum ratios. Doping by HCl after conversion to the emeraldine oxidation state resulted in conductivities in the range from ^ 0.001 to 0.01 S/cm
