Abstract

An organometallic complex which includes a carboxylic acid as an ancillary ligand, and an organic electroluminescent device employing the same. The organometallic complex is useful as a phosphorescence dopant material of an organic electroluminescent device due to its high luminosity in the range of the blue wavelengths.

Description

technical field [0001] The present invention relates to an organometallic complex and an organic electroluminescent device using the same. More specifically, the present invention relates to organometallic complexes with superior luminescent properties in the blue wavelength range. Background technique [0002] An organic electroluminescence display (organic EL display) is an active light-emitting display that utilizes the fact that when an electric current is applied to a thin film composed of a fluorescent or phosphorescent organic compound (hereinafter referred to as "organic film"), the fluorescent or phosphorescent organic compound Light is emitted in response to the recombination of holes injected from the anode and electrons injected from the cathode within the organic film. Moreover, since organic electroluminescent displays have various advantages such as: light weight, simple structure (can be manufactured with uncomplicated manufacturing process), large viewing a...
