Patent ID: 8217195

Claim:
A compound represented by the following Chemical Formula 2: wherein, in the above Chemical Formula 2, A 2 is carbon (C) or silicon (Si), Ar 4 to Ar 7 are the same or different and are independently a substituted or unsubstituted C6 to C20 arylene, X 4 to X 7 are the same or different and are independently selected from the group consisting of hydrogen, a C1 to C5 alkyl, substituents represented by the Chemical Formula 1-1 and substituents represented by the following Chemical Formula 1-2, provided that at least one of X 4 to X 7 is selected from the group consisting of substituents represented by the above Chemical Formula 1-1 and substituents represented by the following Chemical Formula 1-2, and d to g are independently integers of 1 or 2, and when d to g are each equal to 2, each of X 4 to X 7 are the same or different; wherein, in above Chemical Formula 1-1, Z is selected from the group consisting of a single bond, —O—, —COO—, and —OCO—, i is an integer ranging from 1 to 5, h is an integer ranging from 0 to 5, and R 100 is hydrogen or a methyl, provided that when Z is —O—, —COO—, or —OCO—, h is not zero (0), wherein, in the above Chemical Formula 1-2, p and q are independently integers ranging from 1 to 5, and R 101 to R 103 are independently hydrogen or a methyl.
