Embodiment approach
[0105] According to an exemplary embodiment, the L 1 is a single bond, or a substituted or unsubstituted T 1 , the unsubstituted group T 1 is selected from the group consisting of:
[0106]
[0107] where the substituted T 1 There is one or more substituents on it, the substituted T 1 The substituents on are independently selected from deuterium, fluorine, alkyl group with 1 to 4 carbon atoms, alkoxy group with 1 to 4 carbon atoms, alkylthio group with 1 to 4 carbon atoms, A fluoroalkyl group having 1 to 4 carbon atoms, a cycloalkyl group having 5 to 10 carbon atoms, a trialkylsilyl group having 3 to 7 carbon atoms, and a naphthyl group. When the number of substituents is greater than 1, the substituents are the same or different.
[0108] Further optionally, L 1 is selected from a single bond or from the group consisting of:
[0109]
[0110] According to an exemplary embodiment, the L 2 is selected from single bond, substituted or unsubstituted T 2 , the unsub...

[0170] Preparation Example 1. Preparation of Compound 1
[0171]
[0172] 1) Synthesis of intermediate a-I-1
[0173] in N 2 Under the protection, magnesium flakes (2.9g, 120mmol) and 30mL of tetrahydrofuran (THF) were added to the three-necked flask, the temperature of the system was raised to 80°C, and iodine (0.6g, 2.4mmol), 4-bromodibenzofuran were added to the system. (30.0 g, 120 mmol) was completely dissolved in 30 mL of THF solvent, slowly added dropwise to the system within 30 min, and the temperature was controlled at 80° C. during the dropwise addition. After the dropwise addition was completed, the reaction was stirred at 80° C. for 2 h to obtain a mixed solution. After cooling at room temperature, 2,4,6-trichloro-1,3,5-triazine (22.3 g, 120 mmol) dissolved in 80 mL of THF was added dropwise to the mixed solution, and the reaction was terminated after stirring for 3 h to obtain a reaction solution. After the reaction, toluene (200 mL) was added to extract the...
preparation example 2-7
[0185] With reference to the preparation method of sub B-1 in Preparation Example 1, sub B-2 to sub B-4 (hereinafter collectively referred to as sub B-1) were prepared, except that each raw material A was used to replace the process of preparing the intermediate sub B-1. Raw material bromobenzene, adopted raw material A, synthetic target intermediate number and its structure and productive rate are as shown in Table 1.
[0186] Table 1
[0187]
[0188] Intermediates sub A-2 to sub A-5 were prepared by referring to the preparation method of intermediate sub A-1 in Preparation Example 1 (step 1) to step 3)), except that the raw material B in each table 2 was used instead of the preparation The raw material 4-bromodibenzofuran in the intermediate a-I-1, each raw material C is used to replace the raw material 4-bromodibenzofuran in the preparation intermediate a-II-1, the main raw material used, the synthetic target intermediate The body numbers and their structures and yield...
