A novel redox polymer comprised of poly(3,4‐ethylenedioxythiophene) (PEDOT) and ethylenediamine tetraacetic acid‐Ni 2+ (EDTA‐Ni) complex serving as doping anions has been synthesised by a facile one‐step electrochemical approach and utilized as an efficient electrode material for sensitive luteolin detection. The morphology, chemical structure and composition of the redox polymer were analyzed by SEM, UV‐vis and FT‐IR spectrum. Electrochemical tests revealed that the redox polymer was highly electrochemically reversible and exhibited good electrocatalytic activity to the redox reactions of luteolin with a linear range covering from 1 nM to 10 µM with a low detection limit of 0.3 nM of luteolin.
