Claim:
A compound of following Formula 1: wherein at least one of R 11 to R 14 are selected from the group consisting of carbazolyl group, an arylamine group, an arylamine group substituted with an arylamine group, an arylamine group substituted with an arylalkenyl group, an arylalkenyl group substituted with an arylamine group, a bithienyl group substituted with an aryl group, a thienyl group substituted with an aryl group, an imidazolyl group substituted with an aryl group, an aryl group substituted with an imidazolyl group, a benzimidazolyl group substituted with an aryl group, an aryl group substituted with a benzimidazolyl group, a boron group substituted with an alkylaryl group; the remainder of R 11 to R 14 are hydrogen; R 21 to R 25 , R 31 to R 35 , R 41 to R 45 , and R 51 to R 55 are the same or different from each other, and independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted aliphatic cyclic group, an aromatic cyclic group substituted with hetero aromatic cyclic group, a substituted or unsubstituted thienyl group, a substituted or unsubstituted bithienyl group, a substituted or unsubstituted imidazolyl group, a substituted or unsubstituted heterocyclic group containing Si, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted benzimidazolyl group, a condensed ring group formed by two or more rings selected from the above rings, —BR′R″, —NR′R″, —OR', —PR′R″, —SR' and SiR'R″R″', wherein R′, R″ and R″' are each independently selected from the group consisting of a substituted or unsubstituted arylalkyl group, a substituted or unsubstituted arylalkenyl group, a substituted or unsubstituted arylalkynyl group, a substituted or unsubstituted aliphatic cyclic group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aromatic cyclic group, a substituted or unsubstituted heteroaromatic cyclic group and a condensed ring group formed by two or more rings selected from the above rings, provided that R, 11 to R 14 , R 21 to R 25 , R 31 to R 35 , R 45 to R 41 , and R 51 to R 55 are not hydrogen at the same time.
