Embodiment 1

[1120] (Substrate washing)

[1121] A 25 mm x 25 mm x 1.1 mm thick glass substrate with an ITO transparent electrode (manufactured by Geomatec Co., Ltd.) was ultrasonically cleaned in isopropanol for 5 minutes, and then UV ozone was washed for 5 minutes.

[1122] (formation of basal layer)

[1123] On the above-mentioned ITO substrate, CLEVIOUS AI4083 (trade name) manufactured by HERAEUS Co., Ltd. as a hole transport material was formed into a film with a thickness of 30 nm by the spin coating method. After the film formation, unnecessary parts were removed with acetone, and then fired on a hot plate at 200° C. for 10 minutes in the air to produce a base substrate.

[1124] (Formation of luminescent layer)

[1125] Compound H-4 obtained in Synthesis Example 4 was used as a host material, and the following compound D-1 was used as a dopant material, and mixed so that the mass ratio of compound H-4: compound D-1 was 90:10 A mixing ratio of 1.6 mass % was prepared in toluene. ...

Embodiment 2

[1130] An organic EL device was produced in the same manner as in Example 1 except that Compound D-2 was used as a dopant material. The measurement results are shown in Table 1.

Embodiment 3

[1136] Using the compound H-13 obtained in Synthesis Example 13 as the host material and the following compound D-1 as the dopant material, the mixing ratio of compound H-13:compound D-1 reached 95:5 in terms of weight ratio An organic EL element was fabricated by the same method as in Example 1 except that a 1.6% by weight toluene solution was prepared. The measurement results are shown in Table 1.

Abstract

Provided are a compound represented by formula (1) (in the formula, *a, *b, R1, X1, L1, L2, n, A1, and A2 are as defined in the specification) and a method for producing a compound represented by formula (1) that introduces A1 under reaction conditions that make the reaction activity of Hal2 of a compound represented by formula (I) (in the formula, *c, *d, R1, X1, L1, L2, n, A1, A2, Hal1, and Hal2 are as defined in the specification) markedly lower than that of Hal1, then introduces A2 different from A1 under reaction conditions that raise the reaction activity of Hal2. A compound represented by formula (1) can form a layer by coating and can respond to the diverse property requirements of an EL element.

Description

technical field [0001] The present invention relates to a compound, a material for an organic electroluminescent element, an organic electroluminescent element, an ink composition, an electronic device, and a method for producing the aforementioned compound. Background technique [0002] An organic electroluminescent element (hereinafter, sometimes referred to as "organic EL element") is known, which has an organic thin film layer including a light emitting layer between an anode and a cathode, and is formed by injecting Light is emitted from the energy of excitons generated by the recombination of holes and electrons in the light-emitting layer. [0003] Organic EL elements are expected as light-emitting elements with high luminous efficiency, high image quality, low power consumption, and thin design, taking advantage of their advantages as self-luminous elements. It is known to form a light-emitting layer as a host / dopant light-emitting layer in which a host is doped wit...
