Abstract: Polythiophene and Poly(3octylthiophene) were synthesized by direct oxidative polymerization under different temperatures. The chemical structure of samples were characterized by FTIR, XRD, NMR,XPS and UVVis respectively. The results showed that the strcture and the degree of crystallinity(DC) of samples depended on the length of side chain and reaction temperature. Poly(3octylthiophene) has a lower DC.Polythiophene prepared under low temperature has a higher DC. Experimental results suggested that there is certain relationship between DC, chemical structure and conductivity of samples.
