| Popis: | The synthesis of a conjugated copolymer, poly[(i,i'-ferrocenylenevinylene)-co-(2,5-di-n-octyloxy)-p-phenylenevinylene] (PFV-DOPPV) via McMurry coupling of i,i'-ferrocenedialdehyde and 2,5-di-n-octyloxybenzene-i,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. |
