ABSTRACT:
Provided are a conducting polymer film composition comprising a graft copolymer of a self-doped conducting polymer and an organic opto-electronic device comprising a conducting polymer film formed of the above-mentioned composition. In the graft copolymer, the conducting polymer and a polyacid are connected to each other via chemical binding. Therefore, the composition of the present invention can be used in organic opto-electronic devices with minimal or no dedoping occurring from heat generated inside the device. As a result, the present invention can improve efficiency and life-time of the organic opto-electronic device.
