摘要： An organic light-emitting device includes first and second electrodes and a light-emitting layer disposed between the first and second electrodes. The light-emitting layer contains first and second compounds. The first compound is represented by formula [1] or [2]. The second compound is a hydrocarbon compound. In formulae [1] and [2], R1 to R12 and R21 to R32 are each independently selected from a hydrogen atom, alkyl groups, and other groups. Each m is an integer of 1 or more and 3 or less, and each n is an integer of 0 or more and 2 or less, provided that m+n is 3. Each X is a bidentate ligand. Each partial structure IrX is any of the structures illustrated in formulae [3] to [5]. In formulae [3] to [5], R41 to R55 are each independently selected from a hydrogen atom, alkyl groups, and other groups.

摘要： Provided is a photoelectric conversion element including an anode, a photoelectric conversion layer that contains a first organic semiconductor, a second organic semiconductor, and a third organic semiconductor, and a cathode. As each of the first organic semiconductor, the second organic semiconductor, and the third organic semiconductor, a low-molecular weight organic semiconductor is used. The first organic semiconductor, the second organic semiconductor, and the third organic semiconductor have mass ratios that satisfy the following relationship: the first organic semiconductor≥the second organic semiconductor≥the third organic semiconductor. Further, when a total amount of the first organic semiconductor, the second organic semiconductor, and the third organic semiconductor is 100 mass %, a content of the second organic semiconductor is 6 mass % or more, and a content of the third organic semiconductor is 3 mass % or more.
