Patent ID: 8535814

Claim:
A heterocyclic compound comprising a compound represented by Formula 1: wherein each of R 1 , R 4 through R 7 , and R 10 through R 12 is independently selected from the group consisting of hydrogen atoms, heavy hydrogen atoms, substituted and unsubstituted C 1 -C 50 alkyl groups, substituted and unsubstituted C 3 -C 50 cycloalkyl groups, substituted and unsubstituted C 5 -C 50 alkoxy groups, substituted and unsubstituted C 5 -C 50 aryloxy groups, substituted and unsubstituted C 5 -C 50 arylthio groups, substituted and unsubstituted C 5 -C 60 aryl groups, amino groups substituted with at least one R 5 -R 60 aryl group, substituted and unsubstituted C 4 -C 60 heteroaryl groups, substituted and unsubstituted C 6 -C 60 condensed polycyclic groups, halogen atoms, cyano groups, nitro groups, hydroxyl groups, and carboxyl groups, wherein each of R 2 , R 3 , R 8 and R 9 is independently selected from the group consisting of methyl groups and phenyl groups, and wherein two or more neighboring substituents selected from R 1 , R 4 through R 7 , and R 10 through R 12 may optionally bond to each other to form an aromatic ring.
