Electropolymerisation and characterisation of poly[4,4 '-bis(butylsulphanil)-2,2 '-bithiophene]

Electrochemical properties of electrogenerated poly[4,4'-bis(butylsulphanil )-2.3'-bithiophene] have been studied. with particular attention to the cha rge-discharge processes. The possibility of both p- and n-doping is indicat ed. Doping and relevant de-doping processes of the specific polymer have al so been considered in the context of the more general, still un-solved prob lem of the analysis of the mechanisms that al-e operative in the case of si mple polythiophenes. In situ spectroelectrochemical measurements have been used to support the electrochemical results and both in situ UV-visible NIR spectroscopy on neutral, p- and n-doped forms of the polymer, and ex situ IR measurements have been performed.
