The present invention relates to novel thiazolothiazole derivatives and an organic electronic device such as an organic light emitting device, an organic transistor, and an organic solar cell using the same. In the compound of the invention, various substituents are introduced to the core structure, so as to satisfy the requirements such as suitable energy levels, and electrochemical and thermal stability, and also have amorphous or crystalline property depending on the kind of the substituents, so as to satisfy the characteristics individually required for each of the devices. Further, an organic semiconductor of p-type or n-type can be fabricated by introducing various substituents to the core structure having a property of n-type. Therefore, the compound of the present invention can provide a device having higher stability.
