Abstract: The present invention relates to an organoiridium complex for an organic electroluminescent element in which a C—N ligand and an ancillary ligand are coordinated with iridium. This organoiridium complex contains a 2-(dibenzo[b,d]thiophen-4-yl)quinolinate ligand having at least one methyl group introduced thereinto coordinated as the C—N ligand, and is represented by the following Formula. The present inventive organoiridium complex is suitable as a red emitting phosphorescent material for an OLED, has high photoluminescence quantum yield ΦPL, and is excellent in color purity. (In the aforementioned Formula, R1, R2, R3, R4, R5, R6, and R7 are each a methyl group or a hydrogen atom, provided that at least one of R1, R2, R3, R4 is a methyl group; and X—Y is the ancillary ligand.)

Abstract: The present invention is a metal colloid solution comprising: colloidal particles consisting of metal particles consisting of one or two or more metal(s) and a protective agent bonding to the metal particles; and a solvent as a dispersion medium of the colloidal particles, wherein: a chloride ion concentration per a metal concentration of 1 mass % is 25 ppm or less; and a nitrate ion concentration per a metal concentration of 1 mass % is 7500 ppm or less. In the present invention, adsorption performance can be improved with adjustment of the amount of the protective agent of the colloidal particles. It is preferable to bind the protective agent of 0.2 to 2.5 times the mass of the metal particles.

Abstract: The present invention provides an organometallic complex having a high quantum efficiency even in a polymer thin film as a emitting material for organic electroluminescent (EL) element. The present invention relates to an organoiridium complex for an organic electroluminescent element represented by the following Formula; wherein a C—N ligand including two atomic groups (A1, A2), and a β-diketone ligand in line symmetry having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The organoiridium complex of the present invention has a high quantum efficiency even in a polymer thin film with respect to green to yellow electroluminescence. (In the aforementioned Formula, R1, R2, and R3 are each a tert-butyl group or a hydrogen atom, and have at least one tert-butyl group; they may bond each other to thereby form a saturated hydrocarbon ring, when having two tert-butyl groups; A1, A2 are each an unsaturated hydrocarbon ring, at least one is a single ring, and at least one is a heterocyclic ring).
