Compositions of oligoanilines with higher purity, methods of making and using thereof, are provided. The compositions are produced in large scale with larger yield using simple purification techniques such as washing. Methods have been developed that allow large scale synthesis of oligoaniline compounds with the following benefits: (i) higher purity; (ii) larger yield of oligoaniline compounds; (iii) simple purification that does not require complicated techniques such as liquid chromatograph; (iv) lower cost; and (v) full characterization. The highly pure oligoaniline compositions can be used as reducing or oxidizing agent in a redox reaction. The oligoaniline compositions have colors and can be used as dyes, i.e. redox active dyes in a redox reaction, as intermediates for the development of conductive elastomers, or as catalysts.
