[0332] [chemical 18]

[0333] (Synthesis of Intermediate 2)

[0334]

[0335] Under nitrogen flow, 2-(3-pinacolatoborylphenyl)pyridine (17.4 g), Intermediate 1 (19.2 g), 2M aqueous tripotassium phosphate (77 mL), toluene (120 mL) were added to the reaction vessel. ) and ethanol (60 mL), nitrogen was bubbled through for 30 minutes. Thereafter, [Pd(PPh 3 )] 4 (1.21g), stirred and refluxed at 105°C for 1.5 hours. Thereafter, it was cooled to room temperature, and after adding water to perform liquid separation and washing, the organic layer was dried over magnesium sulfate. Thereafter the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chro...

Embodiment 1

[0446] A product obtained by depositing an indium-tin oxide (ITO) transparent conductive film with a thickness of 70 nm on a glass substrate 1 (manufactured by Geomatec, sputtering film-formed product) was patterned to a width of 2 mm using a common photolithography technique and hydrochloric acid etching. The stripes form the anode 2. The patterned ITO substrate is cleaned in the order of ultrasonic cleaning with aqueous surfactant solution, water washing with ultrapure water, ultrasonic cleaning with ultrapure water, and water washing with ultrapure water, and then dried with compressed air , and finally UV ozone cleaning. This ITO functions as the transparent electrode 2 .

[0447] Next, prepare the arylamine polymer containing the following structural formula (P-1), 4-isopropyl-4'-methyldiphenyliodonium tetrakis(pentafluoro) represented by the structural formula (A-1) A coating solution for forming a hole injection layer of phenyl) borate and ethyl benzoate. This coatin...

Abstract

The objective of the present invention is to provide: a novel iridium complex compound; an organic electroluminescent element which achieves an improved element service life by being produced with useof this compound; and a display device and a lighting device, each of which uses this organic electroluminescent element. The present invention relates to an iridium complex compound represented by formula (1).

Description

technical field [0001] The present invention relates to an iridium complex compound, in particular to an iridium complex compound useful as a material for a light-emitting layer of an organic electroluminescence element, a composition containing the compound and a solvent, an organic electroluminescence element containing the compound, and a composition comprising the compound Display devices and lighting of organic electroluminescent elements. Background technique [0002] In recent years, various electronic devices using organic electroluminescence elements (hereinafter referred to as "organic EL elements"), such as organic EL lighting and organic EL displays, have been put into practical use. Organic EL elements are being studied for applications in lighting and displays because of their low applied voltage, low power consumption, and the ability to emit light in three primary colors. In order to realize these, not only the adjustment of the emission wavelength of the li...
