The synthesis of a conjugated copolymer, poly[(1,1′‐ferrocenylenevinylene)‐ co‐(2,5‐di‐ n ‐octyloxy)‐ p ‐phenylenevinylene] ( PFV‐DOPPV ) via McMurry coupling of 1,1′‐ferrocenedialdehyde and 2,5‐di‐ n ‐octyloxybenzene‐1,4‐dialdehyde is reported. PFV‐ DOPPV was fully characterized by 1 H NMR, FTIR, FT‐Raman, UV‐VIS, cyclic voltammetry, size exclusion chromatography (SEC), inductively coupled plasma ‐ optical emission spectrometry (ICP‐OES), thermogravimetry (TG) and differential scanning calorimetry (DSC). The ionization potential, band‐gap energy, electron affinity, HOMO and LUMO levels could be estimated. Electrical measurements in a sandwich device exposed to magnetic fields revealed magnetoresistance.
