Polythiophene (PTh) and a series of conjugated poly(3-alkylthiophene)s (P3ATs), including poly(3-methylthiophene) (P3MT), poly(3-butylthiophene) (P3BT), poly(3-hexylthiophene) (P3HT), poly(3-octylthiophene) (P30T) and poly(3-decylthiophene) (P3DT) were prepared via chemical oxidative polymerization. Except PTh and P3MT, the as-synthesised polymers exhibit both solution and melting processability. Chemical and physical properties of the polymers were characterized by using structural, spectroscopic and thermal analysis. X-ray diffraction study confirmed a layered structure, in which the main chains are stacked on top of each other, forming parallel planes.
