Paragraph 0099-0104, (2020/07/15)
The present invention relates to: a novel organic compound having excellent electron transporting ability and luminescent ability; and an organic electroluminescent device having improved properties such as luminous efficiency, driving voltage, and lifespan by containing the compound in one or more organic material layers. The present invention provides the compound represented by chemical formula 1.COPYRIGHT KIPO 2020
ORGANIC MIXTURE AND APPLICATION THEREOF IN ORGANIC ELECTRONIC DEVICES
-
Paragraph 0198; 0202, (2020/11/27)
The present invention relates to an organic mixture and an application thereof in organic electronic devices. The organic mixture comprises a spirofluorene organic compound containing a fused heterocyclic ring and an aromatic fused heterocyclic organic compound containing an electron-donating group. A combination of the two materials may be used as a host material of a phosphorescent organic light-emitting diode (OLED), which may use the energy of excitons and balance the charge transport to the greatest extent and which may effectively reduce the concentration of excitons and the operating voltage of a corresponding device, thereby effectively improving the efficiency and service life of the related electronic device in order to provide an effective solution for improving the overall performance of an organic electronic device.
Novel organic compounds and organic light-emitting diode therewith
-
Paragraph 0483; 0489-0493, (2018/05/09)
The present invention relates to organic compounds represented by any one of chemical formulas A to D, and an organic light-emitting diode comprising the same. In the chemical formulas A to D, X, R1 to R12, L1, L2, Ar1 to Ar3, n and m are as described in the specification of the present invention. The organic light-emitting diode comprising a compound represented by any one of the chemical formulas A to D may have higher efficiency and longer lifetime compared to the existing diode.COPYRIGHT KIPO 2018
