Molybdenum Carbonyl Complexes with a Polymerizable Phosphorus/Nitrogen/Phosphorus Ligand and Corresponding Conducting Metallopolymers

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 H-1 NMR, P-31{H-1} 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.
