Abstract

The synthesis and characterization of polyferrocenylmethylene (PFM) starting from dilithium 2,2‐bis(cyclopentadienide)propane and a Me₂C[1]magnesocenophane is reported. Molecular weights of up to Mw = 11 700 g mol⁻¹ featuring a dispersity, Ð, of 1.40 can be achieved. The material is studied by different methods comprising nuclear magnetic resonance (NMR) spectroscopy, matrix‐assisted laser desorption/ionization time of flight (MALDI‐ToF) mass spectrometry, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA) measurements elucidating the molecular structure and thermal properties of these novel polymers. Moreover, cyclic voltammetry (CV) reveals quasi‐reversible oxidation and reduction behavior and communication between the iron centers. Also, the crystal structure of a related cyclic hexamer is presented.
