COMPOUND HAVING TRIPHENYLENE RING STRUCTURE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

Provided is a material for use in a high-efficiency organic electroluminescent element, namely a light-emitting-layer host compound that has a high excited-triplet level and is capable of completely sealing in triplet excitons from a phosphorescent light-emitting body. Said compound has a triphenylene ring structure represented by general formula (1). Also provided is a high-efficiency, high-luminance organic electroluminescent element using said compound. Said organic electroluminescent element, which has a pair of electrodes and one or more organic layers sandwiched therebetween, is characterized in that the aforementioned compound is used as a constituent material for at least one organic layer.
