Abstract
Disclosed is an organometallic compound represented by a following Chemical Formula I, wherein the compound is a metal complex including a central coordination metal and a main ligand binding thereto, wherein the main ligand has a structure in which a fused ring is further introduced into 2-phenylquinoline. When the organometallic compound is used as dopant of a light-emitting layer of an organic electroluminescent device, rigidity is imparted to the organometallic compound molecule such that a full width at half maximum (FWHM) is narrow and thus color purity is improved. Further, a non-luminescent recombination process is reduced such that luminous efficiency and lifespan of the organic electroluminescent device are improved. Chemical Formula I is shown below:
