Patent ID: 7413817

Claim:
A compound represented by Formula 1: wherein, X is —Si(A 1 )(A 2 )- or Se, n 1 and n 2 are independently 1 or 2 when X is Se, and n 1 and n 2 are 2 when X is —Si(A 1 )(A 2 )-, and A 1 , A 2 , and R 1 to R 24 are independently a hydrogen atom, a substituted or unsubstituted alkyl group of C 1 -C 30 , a substituted or unsubstituted acyl group of C 1 -C 30 , a substituted or unsubstituted alkoxycarbonyl group of C 1 -C 30 , a substituted or unsubstituted alkoxy group of C 1 -C 30 , a substituted or unsubstituted alkenyl group of C 2 -C 30 , a substituted or unsubstituted alkynyl group of C 2 -C 30 , a substituted or unsubstituted alkylcarboxyl group of C 2 -C 30 , a substituted or unsubstituted aryl group of C 6 -C 30 , a substituted or unsubstituted aralkyl group of C 6 -C 30 , a substituted or unsubstituted aralkyloxy group of C 6 -C 30 , a substituted or unsubstituted heteroaryl group of C 2 -C 30 , a substituted or unsubstituted heteroaryloxy group of C 2 -C 30 , a substituted or unsubstituted aryloxy group of C 6 -C 30 , a substituted or unsubstituted cycloalkyl group of C 4 -C 30 , —N(R)(R′) (provided that R and R′ are independently a hydrogen, an alkyl group of C 1 -C 30 , an aryl group of C 6 -C 30 , or a heteroaryl group of C 2 -C 30 ), cyano, hydroxy, or carboxyl, or at least an adjacent two of R 1 to R 24 are connectable to form a ring.
