Abstract:
Provided is a light-emitting device including an anode, a light-emitting layer, an electron-transporting layer and a cathode. The electron-transporting layer contains at least one electron-transporting material whose LUMO level is −3.0 eV or more and at least one dopant material selected from the group consisting of a heterocyclic compound whose SOMO level is −2.2 to −1.5 eV and a derivative thereof. The LUMO level of the electron-transporting material is smaller than the SOMO level of the heterocyclic compound.

Claim (Index 5):
The light-emitting device according to any one of  claims 1  to  4 , wherein\n the heterocyclic compound is a compound represented by the formula (1-A), and \n the derivative is a compound represented by the formula (1-B) or the formula (1-C): \n wherein\n A 1  represents an oxygen atom, a sulfur atom, \u2014NR 5 \u2014 or \u2014PR 5 \u2014; two A 1  are the same as or different from each other, and at least one A 1  is \u2014NR 5 \u2014 or \u2014PR 5 \u2014; \n R 3  represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, a cycloalkoxy group, an aryloxy group, an alkylsulfenyl group, a cycloalkylsulfenyl group, an arylsulfenyl group, a monovalent heterocyclic group, a halogen atom or a disubstituted amino group; \u2014CH 2 \u2014 in these groups is optionally substituted by an oxygen atom, a sulfur atom, \u2014NR 5 \u2014 or \u2014C(\u2550O)O\u2014, and a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom, provided that adjacent two \u2014CH 2 \u2014 are not substituted at the same time; two R 3  are the same or different and are optionally bonded to each other to form a ring, and a substituent is optionally bonded onto the ring; \n R 4  represents a hydrogen atom, \u2014C(R 6 ) 3 , \u2014OR 7 , \u2014N(R 7 ) 2  or \u2014Si(R 7 ) 3 ; \u2014CH 2 \u2014 in these groups is optionally substituted by an oxygen atom, a sulfur atom, \u2014NR 5 \u2014 or \u2014C(\u2550O)O\u2014, and a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom, provided that adjacent two \u2014CH 2 \u2014 are not substituted at the same time; \n R 5  represents an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group; \u2014CH 2 \u2014 in these groups is optionally substituted by an oxygen atom, a sulfur atom, \u2014NR 8 \u2014 or \u2014C(\u2550O)O\u2014, and a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom, provided that adjacent two \u2014CH 2 \u2014 are not substituted at the same time; when a plurality of R 5  are present, the plurality of R 5  are the same as or different from each other; \n R 6  represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group; a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom; a plurality of R 6  are the same as or different from each other; two R 6  are optionally bonded to form a ring; \n R 7  represents an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group; a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom; a plurality of R 7  are the same as or different from each other; two R 7  are optionally bonded to form a ring; \n R 8  represents an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group; a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom; when a plurality of R 8  are present, the plurality of R 8  are the same as or different from each other; \n R 11  represents an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, a cycloalkoxy group, an aryloxy group, an alkylsulfenyl group, a cycloalkylsulfenyl group, an arylsulfenyl group, a monovalent heterocyclic group or a disubstituted amino group; \u2014CH 2 \u2014 in these groups is optionally substituted by an oxygen atom, a sulfur atom, \u2014NR 5 \u2014 or \u2014C(\u2550O)O\u2014, and a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom, provided that adjacent two \u2014CH 2 \u2014 are not substituted at the same time; and \n X \u2212  represents a counter anion for the cation.
