ABSTRACT:
A heteroacene compound includes a di-thieno-benzo-thieno-thiophene derivative, in which all six rings may be fused together, an organic thin film including the same, and an electronic device that includes the thin film as a carrier transport layer. The compound of example embodiments may have a compact planar structure to thus realize improved solvent solubility and processability. When the compound is applied to electronic devices, a deposition process or a room-temperature solution process may be applied, and as well, intermolecular packing and stacking may be efficiently realized, resulting in improved electrical properties, including increased charge mobility.
