Title:
LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/062277
Kind Code:
A1
Abstract:
Provided is a light-emitting element exhibiting superior light emission efficiency. The light-emitting element has a positive electrode, a negative electrode, and a first organic layer and a second organic layer provided between the positive electrode and the negative electrode, the first organic layer being a layer containing a compound expressed by formula (T) and a fluorescent compound expressed by formula (B), and the second organic layer being a layer containing a cross-linker made out of a cross-linking material. [In the formula, nT1 represents an integer from 0 to 5. nT2 represents an integer from 1 to 10. ArT1 represents a monovalent heterocyclic group of a single or condensed ring, containing a nitrogen atom without a double bond as a ring-constituting atom, and not containing a nitrogen atom with a double bond as a ring-constituting atom. LT1 represents an alkylene group or an arylene group, etc. ArT2 represents a heterocyclic group of a single or condensed ring, containing a nitrogen atom with a double bond as a ring-constituting atom.] [In the formula, n1B represents an integer from 0 to 15. Ar1B represents a condensed-ring aromatic hydrocarbon group. R1B represents an aryl group, a monovalent heterocyclic group, or a substituted amino group, etc.]
