Title:

ORGANOMETALLIC COMPLEX FOR ORGANIC LIGHT-EMITTING LAYER AND ORGANIC LIGHT-EMITTING DIODE

Document Type and Number:

Japanese Patent JP2007254737

Kind Code:

A

Abstract:

To provide an organometallic complex for an organic light-emitting layer and an organic light-emitting diode.

A naphthalene derivative is introduced to the organometallic complex as a ligand. The organic light-emitting diode uses the organometallic complex as a phosphorescent host material. The organic light-emitting diode exhibits high current efficiency, high power efficiency and long lifetime as compared to conventional devices using BAlq.
