ResumoElectrical conductivities and optical absorptions of neutral and oxidized polythiophene films polymerized by the electrochemical method are reported. The electrical conductivity of polythiophene borofluoride film shows metallic value of ca. 100 S cm−1 at room temperature and decreases over 1010 times into semiconductive regime by the electro-chemical or chemical undoping. Absorption spectrum of polythiophene changes by the undoping from the characteristic of metal to interband transition with absorption edge ca. 2.0 eV and maximum absorption coefficient of ∼ 105 cm−1 at 2.7 eV.
