ASYMMETRIC DIKETOPYRROLOPYRROLE POLYMER AND ORGANIC ELECTRONIC DEVICE USING THE SAME

摘要

The present invention relates to a novel asymmetric diketopyrrolopyrrole polymer and uses thereof. According to the present invention, the diketopyrrolopyrrole polymer has high π-electron stacking by introducing an electron donor compound, has high asymmetric arrangement, and thus has high solubility due to an increase in free volume. A solution process is available in an eco-friendly non-halogenated solvent due to the high solubility. The organic electronic device applying the same is capable of performing excellent charge mobility and a remarkable on/off ration, and can be broadly applied to a semiconductor device.
