Organometallic complex, method of preparing the same and organic light emitting device comprising the same

Abstract

An organometallic complex for an organic light emitting device represented by formula 1, a method of preparing the same and an organic light emitting device including the same: where Rthrough Rare a hydrogen atom, a cyano group, a hydroxyl group, a nitro group, a halogen atom, a C-Calkyl group, a C-Calkoxy group, a C-Caryl group, a C-Carylalkyl group, a C-Calkylalkoxy group, a C-Carylalkoxy group, a C-Carylamino group, a C-Calkylamino group, a C-Cheteroarylamino group, and a C-Chetero-ring group; and M is a bivalent metal such as Be, Mg, Zn, Ca, Cr, Fe, Co, Ni and Cu. The compound represented by Formula 1 can be effectively used in an electron transport layer or an electron injection layer. An organic light emitting device including the compound represented by Formula 1 can thus have long lifetime.
