Abstract
Provided is an organic material which can be employed for manufacturing an organic electroluminescent device having a long luminance half-lifetime. The organic material is a composition containing: a borane compound represented by Formula (B1): wherein three Arrepresent an arylene group or a divalent aromatic heterocyclic group; and three Xrepresent an aromatic amino group, a monovalent aromatic heterocyclic group, an alkyl group, or a hydrogen atom; and a conjugated polymer compound represented by Formula (P1): wherein Arrepresents an arylene group, with the proviso that Aris different from Flu; Flurepresents a fluorenediyl group; Hetrepresents a divalent aromatic heterocyclic group; Amrepresents a divalent aromatic amine residue; n, n, nand nare numbers representing molar ratios of Ar, Flu, Hetand Am, respectively, and numbers satisfying 0.4≦n≦1, 0≦n≦0.6, 0≦n≦0.6 and 0≦n≦0.6 when defining n+n+n+n=1.
