COMPOUND AND LIGHT EMITTING ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/162156
Kind Code:
A1
Abstract:
The present invention provides a compound which enables a light emitting element to have excellent luminance life. A compound which is represented by formula (1). (In the formula, n represents an integer of from 2 to 20 (inclusive); each of R1 and R2 independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group or a halogen atom; each Ar1 represents a monocyclic or fused ring arylene group, a monocyclic or fused ring divalent heterocyclic group or a group that is represented by –N(RX1)-; and RX1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group. Incidentally, at least two Ar1 moieties represent specific groups.)
