Title:
CHARGE TRANSPORT MATERIAL, ORGANIC ELECTROLUMINESCENCE ELEMENT, LIGHT-EMITTING DEVICE, DISPLAY APPARATUS, AND ILLUMINATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/133649
Kind Code:
A1
Abstract:
A charge transport material, which has a structure indicated by the following formula, and which comprises a compound containing 6-19 monocyclic aromatic rings (the members of the aromatic ring are carbon atoms or nitrogen atoms, and the number of ring members is 6), has a low driving voltage and excellent durability (R111-R128 indicate hydrogen atoms or substituents thereof. At least one of R111-R122 is a cyano group. However, not all of three continuous benzene rings will each have a cyano group, and a benzene ring having a cyano group will not be substituted by three or more benzene rings).
