A method of synthesizing a fused heteroaromatic compound includes obtaining a first intermediate from a first compound represented by Chemical Formula 1 and a second compound represented by Chemical Formula 2, obtaining a second intermediate including a ring having a chalcogen element from the first intermediate, and obtaining a fused heteroaromatic compound by a cyclization reaction of the second intermediate.

A fused polycyclic heteroaromatic compound represented by Chemical Formula 1, and an organic thin film, an organic thin film transistor, and an electronic device including the fused polycyclic heteroaromatic compound are provided. The fused polycyclic heteroaromatic compound may have a conjugation structure but reinforce planarity among adjacent rings and have further dense packing and thus much increase charge mobility.
