step two, synthesizing an energetic complex: dispersing ligand L in water, heating until all solids disappear, adding aqueous solution of silver salt, dropwise adding corresponding acid until the solids disappear, stirring, cooling to room temperature, standing, filtering, washing with water, and vacuum drying to obtain energetic complex.
5. The method of claim 4, wherein the first step specifically comprises: dissolving 3-amino-1, 2, 4-oxadiazolone and 1, 8-diazabicyclo [5.4.0] undec-7-ene in acetonitrile at room temperature, continuously stirring for 30min, dropwise adding a new methylene dichloride solution of tosyl hydroxylamine, continuously stirring for 3h, stopping the reaction, volatilizing the solvent in air, separating out a crude product, washing with water, filtering, and drying in vacuum to obtain colorless crystals of the ligand L.
6. The process of claim 4 wherein in step one, the molar ratio of 3-amino-1, 2, 4-oxadiazolone, 1, 8-diazabicyclo [5.4.0] undec-7-ene, tosyl hydroxylamine is: 1:1:1.2.
7. The method according to claim 4, wherein in the second step, the heating temperature is 60 ℃.
8. The method according to claim 4, wherein in the second step, the molar ratio of the ligand L to the silver salt is 1:1.
9. Use of an energetic complex based on 1,2, 4-oxadiazolone according to claim 1 as an energetic material.
