摘要
We present some preliminary results of a vibrational spectroscopic investigation carried out on a series of alpha,alpha'-dimethyl end-capped oligothiophenes doped with iodine. The evolution of the doping-induced infrared bands has been followed by means of in situ FT-IR spectroscopy, by allowing thin films of neutral oligothiophenes to react with dry iodine vapours at different concentrations. FT-Raman spectra recorded on powdered samples of I-2-doped alpha,alpha'-dimethylquinquethiophene indicate the existence of a polaron-type defect.
