Title:
PYRROMETHENE BORON COMPLEX, LIGHT-EMITTING ELEMENT CONTAINING SAME, LIGHT-EMITTING ELEMENT, DISPLAY DEVICE, AND ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/149510
Kind Code:
A1
Abstract:
By means of a pyrromethene boron complex represented by general formula (1), provided are: a light-emitting material having a high fluorescence quantum yield and a sharp light-emitting spectrum; and a light-emitting element having a high light-emitting efficiency, color purity, and a durability. (R1-R6 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxyl group, a thiol group, an alkoxy group, an alkylthio group, an aryl ether group, an aryl thioether group, an aryl group, a heteroaryl group, an amino group, a silyl group, a siloxanyl group, and a boryl group. Said groups may also be substituents. Here, at least one among R1 to R4 is a hydrogen atom or an alkyl group. X1 and X2 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxyl group, a thiol group, an alkoxy group, an alkylthio group, an aryl ether group, an aryl thioether group, an aryl group, a heteroaryl group, halogen, a cyano group, an aldehyde group, an acyl group, a carboxyl group, an ester group, an amide group, a sulfonyl group, a sulfonic acid ester group, a sulfonamide group, an amino group, a nitro group, a silyl group, a siloxanyl group, a boryl group, and a phosphine oxide group. Said groups may also be substituents. R7 is represented by general formula (2).) (R8-R10 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxyl group, a thiol group, an alkoxy group, an alkylthio group, an arylether group, an arylthioether group, an aryl group, a heteroaryl group, halogen, a cyano group, an aldehyde group, an acyl group, a carboxyl group, an ester group, an amide group, a sulfonyl group, a sulfonic acid ester group, a sulfonamide group, an amino group, a nitro group, a silyl group, a siloxanyl group, a boryl group, and a phosphine oxide group. Said groups may also be substituents. R11 is selected from the group consisting of an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxyl group, a thiol group, an alkoxy group, an alkylthio group, an arylether group, an arylthioether group, an aryl group, a heteroaryl group, halogen, a cyano group, an aldehyde group, an acyl group, a carboxyl group, an ester group, an amide group, a sulfonyl group, a sulfonic acid ester group, a sulfonamide group, an amino group, a nitro group, a silyl group, a siloxanyl group, a boryl group, and a phosphine oxide group. Said groups may also be substituents. Ar1 is a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group.)
