Document Type and Number:
WIPO Patent Application WO/2013/088959
Kind Code:
A1
Abstract:
This organic electroluminescent element, which has at least one light emitting layer between a positive electrode and a negative electrode, contains a hexadentate coordinated orthometalated iridium complex represented by general formula (I). (In general formula (I), V represents a divalent linking group; L2 and L3 are covalently bonded to each other; each of L1-L3 represents a group represented by general formula (II); X5 and Ir are coordinately bonded to each other; and X7 and Ir are covalently bonded to each other.) (In general formula (II), X1-X5 form a nitrogen-containing heterocyclic ring; X6-X11 form an aromatic five-membered ring or an aromatic six-membered ring; and each of X1-X11 represents a carbon atom or a nitrogen atom, with X4 and/or X5 being a nitrogen atom. In cases where X6-X11 form an aromatic five-membered ring, X11 represents a mere bonding hand.)
