Abstract

There is provided an indolo[3,2,1-jk]carbazole compound having an excellent membrane property, a high T1 energy, and a deep HOMO level. There is also provided an organic light-emitting device that contains the indolo[3,2,1-jk]carbazole compound. There is provided an indolo[3,2,1-jk]carbazole compound having a high T1 energy and a deep HOMO level.

Claims (36)

1. An indolo[3,2,1-jk]carbazole compound represented by the following general formula [1]:

wherein Ar is selected from the substituents listed in the formula [2]

wherein * denotes a site to be bonded to the biphenyl group of the formula [1].

2. An organic light-emitting device, comprising:

a pair of electrodes; and

an organic compound layer between the pair of electrodes,

wherein the organic compound layer contains an indolo[3,2,1-jk]carbazole compound according to claim 1 .

3. The organic light-emitting device according to claim 2 , wherein the organic compound layer is a light-emitting layer.

4. The organic light-emitting device according to claim 3 , wherein the light-emitting layer contains a host material and a guest material, the host material is the indolo[3,2,1-jk]carbazole compound, and the guest material is a phosphorescent material.

5. The organic light-emitting device according to claim 4 , wherein the phosphorescent material is an iridium complex.

6. The organic light-emitting device according to claim 2 , wherein the pair of electrodes are an anode and a cathode, the organic compound layer is a hole-blocking layer, and the hole-blocking layer is in contact with a cathode side of a light-emitting layer.

7. A display apparatus comprising a plurality of pixels, wherein each of the pixels includes an organic light-emitting device according to claim 2 and a switching device connected to the organic light-emitting device.

8. An image input apparatus, comprising:

a display configured to display an image; and
