It is employed Conducting polymer, rechargeable battery electrodes, electrochromic devices, chemical and optical sensors, light-emitting diodes, microelectrical amplifiers, field-effect transistors and non-linear optical materials. It is also used in organic field-effect transistors and in polymer-based solar cells and p-type polymer semiconductor.
Poly(3-octylthiophene-2,5-diyl) (P3OT) is a conducting polymer that is a class of polyalkylthiophene with intrinsic photoluminescence and good electrochemical properties. It can be prepared by oxidative polymerization of 3-octylthiophene (3OT).
