Patent ID: 7714323

Claim:
An organic thin film transistor comprising a gate electrode, an insulating layer, a source electrode, a drain electrode, and at least one organic layer including a semi-conducting layer, wherein at least one of the organic layers comprises a compound represented by the following formula 1: wherein m and n are each 1 or 2, l is 0 or 1, X1 and X2 are each independently CH or N, Y1 and Y2 are each independently NR0 in the case of n=1, and N in the case of n=2, wherein R0 is selected from the group consisting hydrogen, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted aryl group, R1 to R8 are the same or different from each other, and are each independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted arylamine group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted silane group, a substituted or unsubstituted boron group, a substituted or unsubstituted aliphatic cyclic group, a nitrile group (—CN), a nitro group (—NO 2 ), a halogen group, an amide group (—NHCOR, —CONHR, —CONRR′), an ester group (—COOR), a sulfonyl group (—SO 2 R), a sulfoxide group (—SOR), a sulfonamide group (—SO 2 NRR′), a sulfonate group (—SO 3 R), a trifluoromethyl group (—CF 3 ), an amine group (—NHR, —NRR′), and -L-M, and R1 to R8 may be bonded with an adjacent group to form an aromatic, aliphatic or heterocyclic fused ring, L is a C 1 -C 60 alkylene group which is unsubstituted or substituted with at least one group selected from the group consisting of an amine group (—NHR, —NRR′), an amide group (—NHCOR, —CONHR, —CONRR′), an ether group (—COR) and an ester group (—COOR); a C 6 -C 60 arylene group which is unsubstituted or substituted with at least one group selected from the group consisting of an amine group (—NHR, —NRR′), an amide group (—NHCOR, —CONHR, —CONRR′), an ether group (—COR) and an ester group (—COOR); or a 5- to 7-membered heterocyclic group which is unsubstituted or substituted with at least one group selected from the group consisting of an amine group (—NHR, —NRR′), an amide group (—NHCOR, —CONHR, —CONRR′), an ether group (—COR) and an ester group (—COOR), M is selected from the group consisting of an alcohol group (—OH), a thio group (—SH), a phosphate group (—PO 3 H), an amine group (—NHR, —NRR′), a substituted or unsubstituted polyolefin, a substituted or unsubstituted polyvinyl, a substituted or unsubstituted polyacrylate, a substituted or unsubstituted polythiophene, a substituted or unsubstituted polypyrrole, and a substituted or unsubstituted polyaniline, and R and R′are the same or different from each other, and are each independently hydrogen, a substituted or unsubstituted C 1 -C 60 alkyl group, a substituted or unsubstituted C 6 -C 60 aryl group, or a substituted or unsubstituted 5- to 7-membered heterocyclic group.
