Abstract
There are provided an organic light-emitting device having a light output of a high emission efficiency and a high luminance and having high durability and a novel organic compound that enables the device to be attained. An organic compound of a long fluorescence lifetime represented by an organic compound having, in a molecule, at least one partial structure comprising an unsubstituted or substituted indole ring and at least one partial structure comprising an unsubstituted or substituted carbazole ring is used in an organic light-emitting device.
Claims9
An organic compound represented by the following general formula (5):
- wherein R15, R16, R17, R18, R19, and R20 is independently selected from a hydrogen atom, a halogen atom, a linear alkyl group having 1-10 carbon atoms (wherein one methylene group or two or more non-adjacent methylene groups of the alkyl group may be replaced by —O—, and a hydrogen atom in the alkyl group may be replaced by a fluorine atom), an unsubstituted or substituted phenyl group, and an unsubstituted or substituted naphthyl group, with the proviso that at least one of R15, R16, R17, R18, R19, and R20 is a partial structure comprising an indole ring represented by the following general formula (1) and at least another of R15, R16, R17, R18, R19, and R20 is a partial structure comprising a carbazole ring represented by the following general formula (2)
- wherein A1 represents an unsubstituted or substituted phenylene group;
- A2 represents a single bond or an unsubstituted or substituted phenylene group;
- and R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, and R14 are independently selected from a hydrogen atom, a halogen atom, a linear alkyl group having 1-10 carbon atoms (wherein one methylene group or two or more non-adjacent methylene groups of the alkyl group may be replaced by —O—, and a hydrogen atom in the alkyl group may be replaced by a fluorine atom), an unsubstituted or substituted phenyl group, and an unsubstituted or substituted naphthyl group.
