Definitions

  • the present invention includes a novel triphenylene compound having excellent electron transporting ability, hole injection and / or transporting ability, and / or luminous ability, and including the same in at least one organic layer, such as luminous efficiency, luminance, thermal stability, driving voltage, and lifetime. This is an improved organic electroluminescent device.
  • organic light emitting phenomenon refers to a phenomenon in which light appears when electric energy is applied to an organic material.
  • a voltage is applied between the two electrodes, and holes are injected into the organic layer and electrons are injected into the cathode.
  • excitons are formed, and when the excitons fall back to the ground, they shine.
  • organic electroluminescent (EL) devices led to blue electroluminescence using anthracene monocrystals in 1965, based on Bernanose's observation of organic thin film emission in the 1950s.
  • EL organic electroluminescent
  • an organic EL device having a laminated structure divided into a functional layer of a hole layer and a light emitting layer has been proposed, and has been developed in the form of introducing each characteristic organic material layer in the device to make a high efficiency and long life organic EL device.

  • ITO indium tin oxide
  • the reason why the organic EL device is manufactured in multiple layers is that the movement speeds of the holes and the electrons are different. If the appropriate hole injection layer, the hole transport layer, the electron transport layer, and the electron injection layer are made, the holes and the electrons can be effectively transferred. The balance between the holes and the electrons in the device can be achieved to increase the luminous efficiency.
  • Electrons injected from the electron injection layer and holes transferred from the hole injection layer recombine in the emission layer to form excitons, and fall from the singlet excited state to the ground state and are called fluorescence, and fall from the triplet excited state to the ground state.
  • Luminescence is called phosphorescence. Theoretically, when the exciton is generated when the carrier is recombined in the emission layer, the ratio of singlet and triplet excitons is generated at a ratio of 1: 3, and when phosphorescence is used, the internal quantum efficiency may be 100%.
