METHOD FOR PREPARING ORGANIC SEMICONDUCTOR THIN FILM USING AROMATIC ENEDIYNE DERIVATIVES, ORGANIC SEMICONDUCTOR THIN FILM USING METHOD THEREOF AND ELECTRONIC DEVICE USING THE SAME

摘要

Provided are a method for preparing an organic semiconductor thin film simply by solution process, an organic semiconductor thin film prepared by the method which is excellent in chemical and electrical stability and reliance, and an electronic device containing the organic semiconductor thin film as a carrier transport layer. The method comprises the steps of coating a precursor solution comprising an aromatic enediyne derivative represented by formula 1, 2 or 3 and an organic solvent on a substrate to form a coating layer; and heat treating the coating layer to form a thin film, wherein X1, X2, X3, X4, X5, X6, Ar1 and Ar2 are independently a substituted or unsubstituted C3-C30 arylene group or a substituted or unsubstituted C2-C30 heteroarylene group; R1, R2, R3, R4, R5 and R6 are independently H, a halogen atom, a nitro group, an amino group, a cyano group, -SiR1R2R3 (wherein R1, R2 and R3 are independently H or a C1-C10 alkyl group), a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C2-C20 alkenyl group, a substituted or unsubstituted C2-C20 alkynyl group, a substituted or unsubstituted C1-C20 alkoxy group, a substituted or unsubstituted C6-C20 arylalkyl group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C2-C30 heteroaryloxy group, a substituted or unsubstituted C1-C20 heteroalkyl group, or a substituted or unsubstituted C2-C30 heteroarylalkyl group; R1, R2, R3 and R4 are not 0 simultaneously in the formula 1, R5 and R6 are not 0 simultaneously in the formula 2, and R3 and R4 are not 0 simultaneously in the formula 3; a, b, c, d, e and f are independently an integer of 0-10; a+b+c is not 0; and c+d+f is not 0.
