<P>PROBLEM TO BE SOLVED: To provide a new organometallic complex that has a broader emission spectrum in the wavelength range of green to blue, and to provide a light-emitting element using the organometallic complex, and a light-emitting device, electronic equipment and a lighting device using the light-emitting element. <P>SOLUTION: The organometallic complex is represented by a general formula (G1). The organometallic complex represented by the general formula (G1) is a new organometallic complex that exhibits a broad emission spectrum in the wavelength range of green to blue. Further a light-emitting element using the organometallic complex, and a light-emitting device, electronic equipment and a lighting device each using the light-emitting element are provided. (In the formula (G1): R<SP POS="POST">1</SP>represents a 1 to 4C alkyl group, a substituted or unsubstituted 1 to 4C haloalkyl group, or a substituted or unsubstituted 5 to 6C cycloalkyl group; R<SP POS="POST">2</SP>to R<SP POS="POST">4</SP>each independently represents hydrogen, a 1 to 4C alkyl group or a substituted or unsubstituted 6 to 13C aryl group; and R<SP POS="POST">5</SP>represents a 1 to 4C alkyl group, a substituted or unsubstituted 5 to 6C cycloalkyl group or a substituted or unsubstituted 6 to 13C aryl group). <P>COPYRIGHT: (C)2012,JPO&INPIT |
