Abstract:
1. A phenanthrene compound, represented by a formula (1) below where Ar l to Ar 4 each represent an aromatic hydrocarbon ring group having 6 to 18 carbon atoms for forming the ring, the aromatic hydrocarbon ring group comprising none of anthracence skeleton, pyrene skeleton, aceanthrylene skeleton and naphthacene skeleton, wherein Ar 1 to Ar 4 are bonded in any positions of a phenanthrene skeleton; R L is bonded in the 2nd or 9th position of the phenanthrene skeleton and represents a single bond, a substituted or unsubstituted benzene skeleton, naphthalene skeleton, fluorene skeleton, fluoranthene skeleton, triphenylene skeleton, chrysene skeleton, phenyl-naphthalene skeleton, binaphthalene skeleton, benzophenanthrene skeleton, dibenzophenanthrene skeleton, benzotriphenylene skeleton, picene skeleton or benzo[b]fluoranthene skeleton, wherein, when L is a single bond, Ar a represents the number of substituents R b represents the number of the substituents R a and b each represent an integer of 0 to 8; m, n, l and p each represent 0 or 1 while satisfying m+n+l+p≧1 (m,n≧l,p); and a structure represented by a formula (1-X) below is excluded
