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

preparation example 1

[0175] Preparation Example 1 Preparation of Compound 1

[0176] 1) Synthesis of intermediate IM 1-1

[0177]

[0178] 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 organic phase, use anhydrous magnesium sulfate to carry out drying, filter, remove solvent under reduced pressure; Gained crude product uses n-heptane as mobile phase to carry out silica gel column chromatography purification, obtains white solid intermediate IM 1-1 (52.6g, collects rate 55%).

[0179] Intermediate IM 1-2 to IM 1-3 were prepared in the same manner as Intermediate IM 1-1, except that raw material A in Table 1 was used instead of the raw mate...

preparation example 2-6

[0189] 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, intermediate C was used instead of intermediate IM1-1 in Preparation 1. The main raw materials used, the synthesized compounds and their yields and mass spectrometry results are shown in Table 2.
