Title:
ORGANIC MIXTURE, COMPOSITION, ORGANIC ELECTRONIC DEVICE AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2018/095394
Kind Code:
A1
Abstract:
An organic mixture, comprising a first organic compound and a second organic compound that forms an exciplex with the first organic compound. The first organic compound is an aromatic compound containing a triphenylboron heterocycle, and the second organic compound is a compound containing an aromatic fused heterocycle. LUMOH1, HOMOH1 and ET(H1) are respectively defined as the lowest unoccupied orbital, highest occupied orbital and triplet energy level of the first organic compound, and LUMOH2, HOMOH2 and ET(H2) are respectively defined as the lowest unoccupied orbital, highest occupied orbital and triplet energy level of the second organic compound, min((LUMOH1-HOMOH2, LUMOH2-HOMOH1)≤min(ET(H1), ET(H2))+0.1eV.
