Multielectrochromic property of N-phenylnaphthalen-2-amine and N-(4-(1H-pyrrol-1-yl)phenyl)-N-phenylnaphthalen-2-amine

Two conducting polymer films based on N-phenylnaphthalen-2-amine and N-(4-(1H-pyrrol-1-yl)phenyl)-N-phenylnaphthalen-2-amine were successfully prepared via constant potential electrolysis. These two polymer films both exhibited five various colors under different potentials. Cyclic voltammograms showed that the both polymer films have well-defined redox process and reasonable stability. Besides, these two polymer films showed comparatively fast switching time.
