The present invention relates to dioxypyrrolo-heterocyclic compounds and an organic electronic device using the same. The compound of the present invention satisfies the requirements for use in an organic electronic device such as an organic light emitting device, an organic thin film transistor, and an organic solar cell, for example, suitable energy levels, and the electrochemical and thermal stability, by introducing various substituents to the core structure, and also have amorphous or crystalline property depending on the Mnd of the substituents, to satisfy the characteristics individually required for each of the devices. Further, an organic semi-conductor of p-type or n-type can be fabricated by introducing various substituents to the core structure having a property of n-type, thereby providing stability for the device.
