Abstract
To provide an organic electroluminescence element, containing: an anode; a cathode; and at least one organic layer disposed between and the anode and the cathode, the organic layer containing a light-emitting layer, wherein the light-emitting layer contains a host material and a phosphorescent light-emitting material, and the host material contains at least one platinum complex compound containing a tetradentade ligand, expressed by the following general formula 1: where L1 to L3 are each a single bond or a bridging group; R1 to R8 are each a hydrogen atom or a substituent, and at least one of R1 to R8 is a phenyl group or a cyano group; Ra and Rb are each a substituent; and n and m are each an integer of 0 to 3.
Claims4
An organic electroluminescence element, comprising:
- an anode;
- a cathode;
- and
- at least one organic layer disposed between the cathode and the anode, the organic layer comprising a light-emitting layer,
- wherein the light-emitting layer contains a host material and a phosphorescent light-emitting material, and the host material contains at least one platinum complex compound containing a tetradentade ligand, expressed by the following general formula 1:
- where L1, L2, and L3 are each a single bond or a bridging group;
- R1, R2, R3, R4, R5, R6, R7, and R8 are each a hydrogen atom or a substituent, and at least one of R1 to R8 is a phenyl group or a cyano group;
- Ra and Rb are each a substituent;
- and n and m are each an integer of 0 to 3.
