    We have prepared poly(3-octyl-2,2′-bithiophene) and poly(3′-octyl-2,2′;5′2″-terthiophene) and found that they show better stability against thermal dedoping than poly(3-octylthiophene). A reduction of the number of alkyl side chains in a regular way lead to better space for the counter ion on doping, more planar π-system and a more rigid polymer backbone, compared to poly(3-octylthiophene).
