Patent ID: 7927718

Claim:
A compound for an organic EL device having a structure represented by the general formula (2): wherein R 1 , R 2 , R 3 , and R 4 each represent, independently of one another, a halogen atom, a linear or branched alkyl group having 1 to 20 carbon atoms in which one methylene group or at least two non-adjacent methylene groups of the alkyl group may be replaced by —O—,—S—,—CO—,—CO—O—,—O—CO—,—CH═CH—, or —C≡C—, at least one methylene group of the alkyl group may be replaced by an arylene group which may have a substituent or by a divalent heterocyclic group which may have a substituent, and hydrogen atom(s) of the alkyl group may be substituted with fluorine atom(s), an amino group which may have a substituent, a silyl group which may have a substituent, an aryl group which may have a substituent, or a heterocyclic group which may have a substituent; R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , and R 12 each represent, independently of one another, a hydrogen atom, a halogen atom, a linear or branched alkyl group having 1 to 20 carbon atoms in which one methylene group or at least two non-adjacent methylene groups of the alkyl group may be replaced by —O—, —S—, —CO—, —CO—O—, —O—CO—, —CH═CH—, or —C≡C—, at least one methylene group of the alkyl group may be replaced by an arylene group which may have a substituent or by a divalent heterocyclic group which may have a substituent, and hydrogen atom(s) of the alkyl group may be substituted with fluorine atom(s), an amino group which may have a substituent, a silyl group which may have a substituent, a phenyl, naphthyl, pyrenyl, fluorenyl, phenanthrenyl, chrysenyl, fluoranthenyl, triphenylenyl, tetraphenylanthracenyl group which may have a substituent, or a heterocyclic group which may have a substituent, and adjacent ones of R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , and R 12 may be joined to form a ring structure; n represents an integer of 2 to 6.
