Title:
POLYCYCLIC AROMATIC COMPOUND AND COMPOSITION FOR FORMING LIGHT EMITTING LAYER
Document Type and Number:
WIPO Patent Application WO/2016/143624
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a polycyclic aromatic compound which has improved solubility in solvents, film formability, wet coatability and in-plane orientation. The above-described problem is solved by a composition for forming a light emitting layer, which contains, as a first component, at least one compound selected from the group consisting of compounds represented by general formula (A-1) and compounds represented by general formula (A-2), as a second component, at least one compound that has a triplet energy (ET) of 1.8-3.0 eV, and as a third component, at least one organic solvent.
In the formulae, R represents a hydrogen atom, an aryl group, a heteroaryl group, a diarylamino group, a diheteroarylamino group or an aryl heteroarylamino group.
