Title:
ORGANIC COMPOUND AND ORGANIC LIGHT-EMITTING DIODE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/214788
Kind Code:
A1
Abstract:
The present invention relates to an organic compound used in organic layers, such as electron-blocking layers and hole transport layers, within an organic light-emitting diode, and an organic light-emitting diode that adopts the organic compound and display significantly improved device characteristics such as low-voltage operation, longevity, and luminous efficiency. The organic compound according to the present invention exhibits excellent hole injection and transport performance, high capability to confine triplet excitons, superior electron-blocking performance, and excellent stability in thin-film states. The organic light-emitting diode employing the compound in its organic layers, such as electron-blocking and hole transport layers, demonstrate notably superior characteristics in terms of low-voltage operation, longevity, and luminous efficiency compared to conventional devices and thus can be advantageously used in various illumination devices and display devices.
