Problems solved by technology

In order to give full play to the excellent characteristics of organic electronic components, the substances that form the organic layer in the components must first be supported by stable and effective materials, such as: hole injection substances, hole transport substances, luminescent substances, electron transport substances, electron injection substances , luminescence auxiliary layer substances, etc., but stable and effective organic layer materials for organic electronic components have not yet been developed
Existing organic electroluminescent materials still have a lot of room for improvement in terms of luminescence performance, and the industry urgently needs to develop new organic electroluminescent materials

[0190] Preparation Example 1 Preparation of Compound 1

[0191] 1) Synthesis of Intermediate 1-1

[0192]

[0193] Add 1-adamantanol (50.0g, 328.4mmol), bromobenzene (51.6g, 328.4mmol), dichloromethane (DCM, 500mL) into a round-bottomed flask, and cool down to -5~0°C under nitrogen protection. Add trifluoromethanesulfonic acid (73.9g, 492.6mmol) dropwise at -5~0°C, keep stirring for 3h; add deionized water (300mL) to the reaction solution and wash until pH=7, add dichloromethane (100mL) to carry out Extract, combine the organic phases, dry using anhydrous magnesium sulfate, filter, and remove the solvent under reduced pressure; the resulting crude product is purified by silica gel column chromatography using n-heptane as the mobile phase to obtain white solid intermediate 1-1 (52.6g, 55% ).

[0194] Intermediates 1-2 to 1-3 were prepared in the same manner as Intermediate 1-1, except that starting material A in Table 1 was used instead of bromobenzene, the starting materi...

preparation example 2-6

[0204] The following compound was prepared by the same synthetic method as Preparation Example 1, except that the raw material B in Table 2 was used instead of 2-bromo-4,6-diphenyl-[1,3,5]tri Oxyzine, using Intermediate C instead of Intermediate 1-1 in Preparation Example 1. The main raw materials used, the synthesized compounds and their yields and mass spectrometry results are shown in Table 2.
