The redox switching mechanism of conducting polymers is not yet clarified in every respect, the problem of interpretation of the transformation between the insulating and conducting forms of the polymeric film is not yet unambigously solved[1-16]. It is thought that spectroelectrochemical studies on the anodic and cathodic switching of different poly(3'-substituted 2,2':5',2''-terthiophenes) (Fig.1.) could give further information about the processes occurring during the transformation between their insulating and conductive forms owing to a hopefully more regular structure compared to polythiophene considering the molecular level effect of the substituent on the properties of the polymer[2,12].
