Stilbene Derivatives, Light-Emitting Element, Display Device, and Electronic Device |
摘要 |
A novel stilbene derivative is provided with motivation of providing a blue emissive material showing excellent color purity. The use of the stilbene derivative of the present invention allows the fabrication of a blue-emissive light-emitting element with excellent color purity. The invention also includes an electronic device equipped with a display portion in which the stilbene derivative is employed. The stilbene derivative of the present invention is represented by formula (1), in which Ar<SUP>1 </SUP>and Ar<SUP>2 </SUP>may form a 5-membered ring by being directly bonded to each other. In formula (1), A<SUP>11 </SUP>represents any one of substituents represented by general formulas (1-1) to (1-3). The variables shown in formula (1) and (1-1) to (1-3) are as defined in the specification.
