Heteroacene compound, organic thin film comprising the compound, and electronic device comprising the thin film

A method of fabricating an organic thin film, comprising:

• dissolving one or more heteroacene compounds represented by Formula 1 below:
• wherein X1 and X2 are each independently O, S, Se, Te, or N—R, in which R is selected from the group consisting of hydrogen, a C1-12 alkyl group, a C6-12 arylalkyl group, a C6-12 aryl group, a C1-12 alkoxy group, an acyl group, a sulfonyl group, and a carbamate group, and
• R1, R2, R3, and R4 are each independently selected from the group consisting of hydrogen, a substituted or unsubstituted C1-30 alkyl group, a substituted or unsubstituted C1-30 alkenyl group, a substituted or unsubstituted C1-30 alkynyl group, a substituted or unsubstituted C1-30 heteroalkyl group, a substituted or unsubstituted C6-30 arylalkyl group, a substituted or unsubstituted C2-30 heteroarylalkyl group, a substituted or unsubstituted C5-20 cycloalkyl group, a substituted or unsubstituted C2-30 heterocycloalkyl group, a substituted or unsubstituted C6-30 aryl group, and a substituted or unsubstituted C2-30 heteroaryl group, in an organic solvent to form a solution;
• and
• applying the solution to a substrate.
