Claim:
An organic luminescence device, comprising: a pair of an anode and a cathode, and at least one organic layer disposed between the anode and the cathode, wherein said at least one organic layer comprises a layer comprising at least one species of a compound represented by any one of the following formulas (III-b) to (IX-b): wherein R 1 to R 4 independently denote a hydrogen atom, an alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, an alkoxy group, a nitro group, or a substituted or unsubstituted amino group; and L 1 , L 2 , L 3 and L 4 independently denote a hydrogen atom, an alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, an alkoxy group, a nitro group, a substituted or unsubstituted amino group, or a group represented by any one of the following formulas (X), (XI) and (XII): wherein R 5 to R 15 independently denote a hydrogen atom, an alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, or a nitro group; X 1 to X 3 and Y 1 to Y 3 independently denote a nitrogen atom or C—R 16 where R 16 denotes a hydrogen atom, an alkyl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted aryl group; Z 1 to Z 3 independently denote —O—, —S—, —NR 17 —, —Si(R 18 )R 19 —, —C(R 20 )R 21 —, —CH═CH— or —CH═N— in which R 17 , R 20 and R 21 independently denote a hydrogen atom, an alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; and R 18 and R 19 independently denote an alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; l and p are independently 0 or 1; m and n are independently 0 or an integer of 1-30, with the proviso that m+n is an integer of 1-30; and q and r are independently an integer of 2-30.
