Abstract

Methacrylamide polymers with pendant monodentate, bidentate, and tridentate phosphine ligands (poly-P₁, poly-P₂, and poly-P₃, respectively) have been synthesized. These polymers react with Mo(N₂)₂(PPh₂Me)₄ to form polymers with bound molybdenum dinitrogen complexes. Similarly, MoCl₃(THF)₃ reacts with poly-P₃ to form MoCl₃(poly-P₃). These polymers have been used to modify silicon and carbon electrodes. These electrodes have been characterized by cyclic voltammetry and FT-IR spectroscopy. The redox chemistry of electrodes modified with Mo(N₂)₂(poly-P₃)PPh₂Me and Mo(N₂)₂(poly-P₂)₂ on silicon and carbon electrodes closely parallels that observed for their solution counterparts. However, reduction of MoCl₃(poly-P₃) and MoCl₃(poly-P₂)₂ on silicon and carbon electrodes does not lead to formation of polymer-bound molybdenum dinitrogen complexes.
