Original Titel:
Infrared spectroelectrochemical investigations on the doping of soluble poly(isothianaphthene methine) (PIM)
Sprache des Titels:
Englisch
Original Kurzfassung:
Attenuated total reflection Fourier transform infrared (ATR-FTIR) investigations on the doping processes in substituted poly(isothianaphtene methine) (PIM), a new low band gap conjugated polymer, are reported. The doping was studied in situ during chemical p-doping (oxidation) by
iodine and during electrochemical p-doping (oxidation) and n-doping
(reduction). During both signs of doping, infrared active vibrational
(IRAV) bands due to strong coupling of the electrons to lattice vibrations are observed. The results are compared to FT-Raman spectra. Electrochemical p-doping shows two different doping regimes depending on the electrochemical potential. The narrow linewidth and low absorption intensities of the IRAV bands indicate a strong localization of the doping induced charge carriers, which is ascribed to a tilted geometry of the conjugated backbone due to steric repulsion effects.
