Ionization treatment of pyrazolo[4,3-c]pyrazole derivatives to achieve the low sensitivity of high-energy materials

Low mechanical sensitivity is an evaluation index for the development of safe and stable high-energy materials. Herein, 3,6-Dinitropyrazolo[4,3-c]pyrazole (DNPP) and its ionic salts 1 - 4 with a fused-ring backbone were synthesized...
