Sammanfattning
An electrically conducting copolymer film, poly(2-biphenyl-3-octylthiophene) (PBOT), was electropolymerized from the comonomer 2-
biphenyl-3-octylthiophene (BOT) and characterized by both ex situ and in situ spectroelectrochemical techniques: UV–vis spectroscopy,
FTIR spectroscopy and resonance Raman spectroscopy. The formed copolymer was compared with a copolymer synthesized from a mixture
of 3-octylthiophene and biphenyl, poly(thienyl biphenyl) (PTB). All spectroscopic measurements gave evidence of formation of a conductive
material with high content of short phenylene segments but with an effective conjugation length shorter than in the PTB copolymer film. The
structure of PBOT was also less crosslinked having more para-substitution than the structure of PTB.
