Embodiment 1
[0032] Embodiment 1: the synthesis of compound 1
[0033] Material 1 (SM-1) and 3 equivalents of base (NaOH) were dissolved in an appropriate amount of DMF (N,N-dimethylformamide), and replaced with nitrogen three times. Then weigh 3 equivalents of material 2 (SM-2) and dissolve it in an appropriate amount of DMF, add it dropwise to the above solution at room temperature under the protection of nitrogen, and stir the reaction overnight. After the reaction, the reaction solution was poured into water to precipitate a white solid, and the obtained solid was fully washed with water and alkaline solution to obtain the target product 1, the yield: 85%, elemental analysis: C, 87.95%; H, 5.80%; N, 2.87% (measured value); C, 87.98; H, 5.82; N, 2.89 (C 71 h 56 N 2 o 2 Theoretical value), hydrogen spectrum such as figure 1 shown.

Embodiment 2
[0036] Embodiment 2: the synthesis of compound 2
[0037] Material 3 (SM-3) and 3 equivalents of base (KOH) were dissolved in an appropriate amount of DMF, and replaced with nitrogen three times. Then weigh 3 equivalents of material 2 (SM-2) and dissolve it in an appropriate amount of DMF, add it dropwise to the above solution at room temperature under the protection of nitrogen, and stir the reaction overnight. After the reaction, the reaction solution was poured into water to precipitate a white solid, and the obtained solid was fully washed with water and lye to obtain the target product 2, the yield: 90%, elemental analysis: C, 87.65%; H, 6.87%; N, 2.49% (measured value); C, 87.69; H, 6.90; N, 2.52 (C 81 h 76 N 2 o 2 theoretical value).

Embodiment 3
[0040] Embodiment 3: the synthesis of compound 3
[0041] Material 4 (SM-4) and 3 equivalents of base (NaH) were dissolved in an appropriate amount of DMF, and replaced with nitrogen three times. Then weigh 3 equivalents of raw material 2 (SM-2) and dissolve it in an appropriate amount of DMF, and add it dropwise to the above solution under the protection of nitrogen at room temperature, and stir the reaction overnight. After the reaction, the reaction solution was poured into water to precipitate a white solid, and the obtained solid was fully washed with water and lye to obtain the target product 3, the yield: 60%, elemental analysis: C, 87.60%; H, 7.25%; N, 2.41% (measured value); C, 87.59; H, 7.26; N, 2.40; (C 85 h 84 N 2 o 2 theoretical value).
