Polythiophene is chemically synthesized and doped with FeCl3 for 2.5, 5 and 10 h. For structural investigation all samples have been characterized using different techniques. The results of elemental analysis show that with the increase of doping duration the Fe content increases while the S content decreases. FTIR spectrum reveals the complex formation between FeCl3 and polythiophene. UV-Visible results have been used to calculate band gap energy.
