A novel poly(aryl ether ketone) bearing pendant aniline tetramers (PAEK‐p‐AT) is prepared through nucleophilic aromatic polycondensation. Structures are confirmed via nuclear magnetic resonance, Fourier‐transform infrared spectra, and X‐ray diffraction. The electrochemical activity of PAEK‐p‐AT is explored by cyclic voltammetry in 1.0 M H 2 SO 4 and confirms a surface controlled process. Moreover, the doped PAEK‐p‐AT shows a high dielectric constant at room temperature during dielectric testing. The electrochromic performance of a PAEK‐p‐AT film is investigated by spectrochronoamperometry in detail, exhibiting good electrochromic properties with high contrast value, satisfactory coloration efficiency, and moderate switching times.
