Abstract
Official abstract text for this publication.
An organic compound having an excellent electron injection and transport performance is provided as a material for a low-power-consumption organic electroluminescent device. A low-power-consumption organic electroluminescent device is also provided by using the compound. The compound is a compound of general formula (1) or (2) having a substituted bipyridyl and triphenylene ring structure. The organic electroluminescent device includes a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes, and uses the compound as constituent material of at least one of the organic layers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compound having a substituted bipyridyl and triphenylene ring structure, wherein the compound is represented by the following general formula (2′) wherein R 19 to R 39 may be the same or different, and represent a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, cyano, trifluoromethyl, linear or branched alkyl of 1 to 6 carbon atoms that may have a substituent, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group, and wherein n3, n4, and n5 may be the same or different, and represent 2 or 3, and the plurality of R 22 to R 30 may be the same or different, respectively.
