US 8,795,851 B2 · Organometallic complex, light-emitting element, light-emitting device, electronic device, and lighting device

Abstract

An object is to provide a novel organometallic complex that has a broader emission spectrum in the wavelength range of green to blue. Other objects are to provide a light-emitting element using the organometallic complex, and a light-emitting device, an electronic device, and a lighting device each using the light-emitting element. Provided is an organometallic complex represented by a general formula (G1). Represented by the general formula (G1) is a novel organometallic complex that exhibits a broad emission spectrum in the wavelength range of green to blue. Further provided are a light-emitting element using the organometallic complex, and a light-emitting device, an electronic device, and a lighting device each using the light-emitting element.
