ORGANOMETALLIC COMPLEX, LIGHT-EMITTING ELEMENT, DISPLAY, ELECTRONIC DEVICE, AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a new substance exhibiting phosphorescence.SOLUTION: The new substance is an organometallic complex represented by general formula (G1). In general formula (G1), Rrepresents a 1-9C haloalkyl group which may have a substituent. In addition, Rrepresents any of a 1-6C alkyl group, a 5-8C cycloalkyl group which may have a substituent, and a 6-12C aryl group which may have a substituent. Further, Ar represents a 6-13C arylene group which may have a substituent. M represents either a group 9 element or a group 10 element.
