Fused polycyclic heteroaromatic compound, organic thin film including compound and electronic device including organic thin film

摘要

A low-molecular-weight fused polycyclic heteroaromatic compound may have a compact planar structure in which seven or more rings are fused together, and thereby exhibits high charge mobility, and furthermore, enables the use of a deposition process or a room-temperature solution process when applied to devices, therefore realizing improved processibility. An organic thin film and electronic device may include the fused polycyclic heteroaromatic compound.
