Patent ID: 8435648

Claim:
A compound for an organic photoelectric device, the compound being represented by the following Chemical Formula 1: wherein, in Chemical Formula 1, A 1 to A 10 are each independently selected from the group of CR 1 to CR 10 , SiR 1 to SiR 10 , and N, wherein at least two adjacent ones of R 6 to R 10 are fused to each other to form an aromatic fused ring, provided that: the ring including A 1 to A 5 is a pyridinylene ring in which exactly one of A 1 to A 5 is N, at least one of A 6 to A 10 is N, or at least one atom of the aromatic fused ring formed by fused ones of adjacent ones of R 6 to R 10 is N, and at least two of A 6 to A 10 are selected from the group of CR 6 to CR 10 and SiR 6 to SiR 10 , R 1 to R 10 are each independently selected from the group of hydrogen, a halogen, a nitrile group, a cyano group, a nitro group, an amide group, a carbonyl group, an ester group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkenylene group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted alkynylene group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted cycloalkylene group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted arylene group, Ar 1 is an unsubstituted arylene group or an arylene group substituted only with a halogen, a nitrile group, a cyano group, a nitro group, an amide group, a carbonyl group, an ester group, an alkyl group, an alkoxy group, an alkenyl group, an alkynyl group, a cycloalkyl group, an aryl group, or a combination thereof, Ar 2 is a substituted or unsubstituted aryl group, and l is an integer ranging from 2 to 4, and m is an integer ranging from 1 to 4, wherein each of the 2 to 4 l units are the same, and wherein, when m is 2 or more such that there are 2 or more m units, each of the 2 or more m units are the same or different.
