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.
