摘要

Increase the luminous efficiency of a light emitting device emitting near infrared light.The reliability of light emitting devices emitting near infrared light is enhanced.Problem to be solved: to provide a light emitting device using an organic compound exhibiting light emission having a maximum peak wavelength of 760 nm or more and 900 nm or less.An organic metal complex represented by general formula (G1) is provided.In Formula 1, R1 to R11 independently represent hydrogen groups of hydrogen or carbon numbers greater than or equal to 1 or 6, and at least two of R1-R4 and at least two of R5 to R9 represent alkyl groups of carbon numbers greater than or equal to 1 and X, respectively A substituted or unsubstituted benzene ring or naphthalene ring, n is 2 or 3, and l represents a monoanionic ligand.
