Evolution of Oxidizing Inorganic Metal Salts：Ultrafast Laser Initiation Materials Based on Energetic Cationic Coordination Polymers

An effective and novel design strategy for ultrafast laser initiating materials has been established on the basis of coordination chemistry for the first time in the present work. In view of the positive effect of Ag ion and perchlorate on laser sensitivity, silver perchlorate as a representative of oxidizing inorganic metal salts was used to construct energetic cationic coordination polymer (ECCPs), which solved the embarrassing situation that these salts are difficult to be directly applied in energetic materials because of unavoidable hygroscopicity and physical mixtures inhomogeneity of oxidant and reductant. With non-energetic nitrogen-rich ligand 3-amino-1H-1,2,4-triazole-5-carbohydrazide (ATCA), one new laser-sensitive Ag(I) based ECCP [Ag(ATCA)ClO4]n (1) was successfully synthesized with compact helical structure proved by X-ray single diffraction crystal data. The physicochemical property evaluation revealed that this Ag-ECCP not only completely discarded the undesirable properties of the silver ...
