Definitions
- the present specification relates to a compound and an organic light emitting device including the same.
- the organic light emitting phenomenon refers to a phenomenon that converts electrical energy into light energy using an organic material.
- An organic light emitting device using an organic light emitting phenomenon usually has a structure including an anode and a cathode and an organic material layer therebetween.
- the organic material layer is often composed of a multi-layered structure composed of different materials, for example, may be formed of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like.
- Patent Document WO2017-018326 A1
- This specification is intended to provide a compound and an organic light emitting device comprising the same.
- A1 to A3 are the same as or different from each other, and each independently an substituted or unsubstituted aromatic hydrocarbon ring; Or a substituted or unsubstituted aromatic heterocycle,
- X is B or N
- Y is N(R11), Z is O; S; Or N(R12),
- Y is O; S; Or N(R11), Z is N(R12),
- R1 is a substituted or unsubstituted aryl group
- R2 is a substituted or unsubstituted alkyl group; Or a substituted or unsubstituted aryl group,
- R11 is -(L11)n11-Ar1
- R12 is -(L12)n12-Ar2
- L11 and L12 are the same as or different from each other, and each independently a direct bond; A substituted or unsubstituted arylene group; Or a substituted or unsubstituted divalent heterocyclic group,
- Ar1 and Ar2 are the same as or different from each other, and each independently deuterium; Halogen group; Nitrile group; A substituted or unsubstituted alkyl group; A substituted or unsubstituted cycloalkyl group; A substituted or unsubstituted haloalkyl group; A substituted or unsubstituted silyl group; A substituted or unsubstituted aryl group; Or a substituted or unsubstituted heterocyclic group,
- n11 and n12 are the same as or different from each other, and each independently 1 or 2,
- L11 is the same as or different from each other
- L12 is the same as or different from each other.
- the present specification is a first electrode; A second electrode provided to face the first electrode; And an organic light emitting device including at least one layer of an organic material provided between the first electrode and the second electrode, wherein at least one layer of the organic material layer includes a compound represented by Chemical Formula 1 do.
- the compound according to the exemplary embodiment of the present specification is used in an organic light emitting device, so that a driving voltage of the organic light emitting device can be lowered and light efficiency can be improved.
- the lifespan characteristics of the small intestine can be improved by the thermal stability of the compound.
- 1 to 3 show an example of an organic light emitting device according to an exemplary embodiment of the present specification.
- Figure 4 shows the luminous efficiency (Example 14) according to the doping concentration of the compound A-2 according to an exemplary embodiment of the present specification.
- the compound represented by Chemical Formula 1 has a structure in which a polycyclic ring is condensed, and the A1 ring and the A2 ring are connected by carbon (bridge alkyl site). By connecting the two rings, it is possible to lower the overall fluidity of the structure and obtain a narrow half-width light emission wavelength. In addition, by introducing various substituents such as an alkyl group and an aryl group at the bridge alkyl site, the emission wavelength can be adjusted. In addition, the polycyclic structure is excellent in stability, and when used as a dopant in the light emitting layer of the organic light emitting device has long life and high efficiency characteristics.
- the bulk of the three-dimensional structure of the molecule is bulky compared to the structure in which only the alkyl group is connected (bulky). It is possible to increase, and the interaction between the host and the dopant is reduced, thereby improving the life of the device.
- Cn refers to n carbon atoms.
- Cn-Cm refers to n to m carbon atoms.
- substitution means that the hydrogen atom bonded to the carbon atom of the compound is replaced with another substituent, and the position to be substituted is not limited to a position where the hydrogen atom is substituted, that is, a position where the substituent is substitutable, and when two or more are substituted , 2 or more substituents may be the same or different from each other.
