NOVEL DIKETOPYRROLOPYRROLE POLYMER AND ORGANIC ELECTRONIC ELEMENT USING SAME

The present invention relates to an organic semiconductor compound for an organic electronic element such as an organic thin film transistor (OTFT), and to a use therefor. More specifically, the present invention relates to: a diketopyrrolopyrrole polymer constituting a novel organic semiconductor compound having high pi-electron overlap by introducing an electron donor compound into a diketopyrrolopyrrole derivative; and an organic electronic element in which charge mobility and on/off ratio are improved by using the diketopyrrolopyrrole derivative as an organic semiconductor layer.
