The design, synthesis, and characterization of the novel polymerizable ligand 3,5‐bis(3,4‐ethylenedioxythien‐2‐yl)‐ N,N ‐bis(2‐diphenylphosphinoethyl)‐phenylamine is achieved. The corresponding molybdenum complexes (EDOT) 2 PNP‐Mo(CO) n where n = 3,4 with carbonyls as ancillary ligands are also synthesized, and characterized by 1 H NMR, 31 P{ 1 H} NMR, HRMS, FTIR (both the solution state spectrum between KBr discs and the solid‐state spectrum with attenuated total reflectance [ATR] apparatus). Single crystal X‐ray analysis of (EDOT) 2 PNP‐Mo(CO) 3 complex is performed. The monomer complexes and the free ligand are electropolymerized to obtain the corresponding polymers that are studied electrochemically. The Mo/P and Mo/S ratios as well as the metal oxidations in the conducting metallopolymers are analyzed by X‐ray photoelectron spectroscopy.
