Title:
NOVEL CERIUM COMPLEX, AND LIGHT EMITTING MATERIAL
Document Type and Number:
Japanese Patent JP2019142829
Kind Code:
A
Abstract:
To provide a novel cerium carbene complex suitable for LED phosphors, organic EL emission layer materials, wavelength conversion materials for solar cells, and wavelength conversion materials for agriculture facility, and a method of producing the same.SOLUTION: The present invention provides a cerium complex with trivalent cerium coordinated with a carbene compound; particularly, a cerium complex in which the carbene compound coordinated to trivalent cerium being represented by formula (1). (R, R, R, R, R, R, R, R, R, Reach represent a hydrogen atom, or a C1-20 hydrocarbon group, or a hydrocarbon group containing an oxygen atom or a phosphorus atom, where they may be bound to each other, to form a ring. R, Reach represent a hydrogen atom or a C1-20 hydrocarbon group, where they may be bound to each other, to form a ring. x is an integer of 0 to 10).SELECTED DRAWING: None
