Embodiment 1

[0256] Embodiment 1 (use compound (1) to prepare organic EL device as hole injection material)

[0257] A 25mm×75mm×1.1mm thick glass substrate (manufactured by GEOMATEC) having an ITO transparent electrode was cleaned using ultrasonic waves in isopropanol for 5 minutes, and then exposed to ozone generated by ultraviolet light for 30 minutes. On the surface of the cleaned substrate on the transparent electrode side, a solution obtained by dissolving compound (1) in toluene was coated according to the spin coating method (thickness of formed film: 20 nm). The formed film was fully dried at 100° C. under vacuum. Attach the dried laminate to the substrate holder of the vacuum vapor deposition apparatus. According to the vacuum vapor deposition method, the following compounds were sequentially laminated on the attached laminated material and an organic EL device was obtained: the following compound HT1 for the hole transport layer (thickness of the formed layer: 20 nm), HT1 for t...

Abstract

An amine compound having a specific structure; and an organic electroluminescent element which comprises an anode and a cathode and, sandwiched therebetween, an organic thin film layer consisting of one or more layers comprising at least a luminescent layer, wherein at least one layer of the organic thin film layer has an excellent property balance among a low ionization potential, high band gap energy, high injection efficiency, and high mobility and has high heat resistance and a high luminescent efficiency.

Description

technical field [0001] The present invention relates to an amine compound (hereinafter referred to as "amine-based compound") and an organic electroluminescent (hereinafter "electroluminescent" and "electroluminescent" will be referred to as "EL") element (hereinafter referred to as "EL") using the compound An "EL element" will be referred to herein as an "EL device"). More specifically, the present invention relates to an organic EL device having excellent heat resistance and luminous efficiency and an amine-based compound capable of obtaining the device. Background technique [0002] The organic EL device is a self-luminous device utilizing the principle that when an electric field is applied, a fluorescent substance emits light using energy of recombination of holes injected from an anode and electrons injected from a cathode. Organic EL devices have excellent visibility due to self-luminescence and excellent impact resistance due to an all-solid ...
