wherein R 1 and R 2 are each independently selected from a tertiary butyl group, an adamantyl group, and a bicyclooctyl group, R 3 is selected from a hydrogen atom, a halogen atom, and a cyano group, R 4 and R 5 are each independently selected from a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an alkoxy group, and an amino group, and R 6 is an alkyl group.
2. The iridium complex according to claim 1 , wherein both the R 1 and R 2 are tertiary butyl groups.
3. The iridium complex according to claim 1 , wherein the R 6 is a methyl group.
4. The iridium complex according to claim 1 , wherein the iridium complex emits blue light.
5. A material for an organic light-emitting element comprising the iridium complex according to claim 1 .
6. An organic light-emitting element comprising a pair of electrodes and an organic compound layer disposed between the pair of electrodes,
wherein the organic compound layer contains the iridium complex according to claim 1 .
7. The organic light-emitting element according to claim 6 , wherein the organic compound layer is a light-emitting layer, the light-emitting layer includes a host material and a guest material, and the guest material contains the iridium complex.
8. A display device comprising a plurality of pixels, each of the pixels including the organic light-emitting element according to claim 6 and a switching element connected to the organic light-emitting element.
9. An illuminating device comprising the organic light-emitting element according to claim 6 .
10. An electrophotographic image forming apparatus comprising an exposure light source, wherein the exposure light source comprises the organic light-emitting element according to claim 6 .
