Organic electric light emitting element, material for said element, and light emitting device, display device, and illumination device employing said element

Abstract

An organic electroluminescent element including a substrate, a pair of electrodes including an anode and a cathode, disposed on the substrate, and at least one organic layer including a light emitting layer, disposed between the electrodes, in which the organic layer includes a compound represented by the following general formula, has high luminous efficiency, excellent blue color purity, and a small change in the chromaticity due to deterioration by driving (Cy represents a fused aromatic ring structure having the number of constituent rings of 3 or more, and has Dnand Acas different constituent rings, and each of the constituent rings are all hydrocarbon rings. Dnrepresents NR, an O atom, or an S atom. Acrepresents an electron absorbing substituent, an aryl group having an electron absorbing substituent, or an electron deficient heteroaryl group. The ring Zrepresents an arylene group or a heteroarylene group. L, Land Lrepresent specific linking groups. u1 represents 0 or 1, and in the case where u1 is 1, the ring thus formed is not an aromatic ring. n1 and q1 represent 0 or 1, and in the case where any one of n1 and q1 is 0 and n1 or q1 is 1, the rings thus formed are not all aromatic rings. When Acis a pyridine ring, at least one of n1 and q1 is 1.)
