The electrochemically synthesized conducting copolymer consisting of 3-octylthiophene and biphenyl units has been characterized by in situ
resonance Raman spectroscopy, UV–visible spectroscopy, in situ FTIR attenuated total reflectance spectroscopy and cyclic voltammetry. The
structure of the formed material is compared with the two homopolymers: poly(3-octylthiophene) or poly(paraphenylene). The results show that
the thiophene segments are longer than the phenylene segments in the poly(thienyl biphenyl) film formed. During electrochemical doping the
Raman spectra indicate changes in the polymer backbone that can be assigned to transformation of the neutral form into the charged form.
