Definitions
- the present specification relates to a polymer and an organic light emitting device formed using the same.
- the organic light emitting phenomenon is one example in which electric current is converted into visible light by an internal process of a specific organic molecule.
- the principle of the organic light emitting phenomenon is as follows. When the organic material layer is placed between the anode and the cathode, when a current is applied between the two electrodes, electrons and holes are injected into the organic material layer from the cathode and the anode, respectively. Electrons and holes injected into the organic material layer recombine to form excitons, and the excitons fall back to the ground state and emit light.
- An organic electroluminescent device using this principle is generally a cathode, an anode, and an organic material layer positioned therebetween, for example, an organic material layer including a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer.
- pure organic materials or complex compounds in which organic materials and metals are complexed occupy most of the materials.
- the hole injection material or the hole transport material an organic material having a p-type property, that is, an organic material that is easily oxidized and has an electrochemically stable state upon oxidation is mainly used.
- the electron injection material or the electron transport material an organic material having an n-type property, that is, an organic material that is easily reduced and has an electrochemically stable state upon reduction is mainly used.
- a material having both p-type and n-type properties that is, a material having a stable form in both oxidation and reduction states, is preferred, and a material with high luminous efficiency that converts excitons into light when formed desirable.
- the material used in the organic light emitting device additionally has the following properties.
- the material used in the organic light emitting device has excellent thermal stability. This is because joule heating occurs due to the movement of electric charges in the organic light emitting diode.

- the material used for the organic light emitting device must have excellent chemical stability, charge mobility, and interfacial properties with an electrode or an adjacent layer. That is, the material used for the organic light emitting diode should be less deformed by moisture or oxygen.
- the density of holes and electrons in the light emitting layer of the organic light emitting device should be balanced to maximize exciton formation.
- the interface with the electrode including the metal or metal oxide should be good.
- the material used in the organic light emitting device for the solution process should additionally have the following properties.
