Energetic 1H-Imidazo[4,5-d]pyridazine-2,4,7-triamine: A Novel Nitrogen-rich Fused Heterocyclic Cation with High Density

Abstract: Fused heterocyclic energetic cation was rarely reported despite the development of energetic cation has attracted increasing attention in recent years. In this work, a new 1H-imidazo­[4,5-d]­pyridazine-2,4,7-triamine was synthesized in a one-step reaction, which was used as a cation to prepare 1H-imidazo­[4,5-d]­pyridazine-2,4,7-triamine perchlorate. Interestingly, when the synthesis was accomplished in different conditions, two crystal forms of perchlorate α-4 and β-4 were obtained, which were further confirm… Show more

“…Unfortunately, due to the high sensitivity of CL-20 and HMX, the improvement of sensitivity performance is still limited even if it is regulated by a crystal engineering strategy, while the energy performance of FOX-7 and LLM-105 is also difficult to be sufficiently improved by crystal engineering research. Therefore, the direct crystal regulation of high-energy and low-sensitivity energetic materials will provide more opportunities for obtaining the explosives with better comprehensive performance. …”

“…Taking into account, our efforts have continued in the last years studies on isoxazole and oxadiazole derivatives in searching for new biological active derivatives. [5][6][7] Although, there are known molecules with positive charge localized at the nitrogen atom, [8][9][10][11] in the literature there is less mentioned about compounds possessing local positive charge at the carbon atom, and they are limited to small molecules. 12,13 Tailoring the chemical and physical properties of molecules by rational planning to improve overall stability, solubility or to reduce toxicity when designing new compounds with expecting application in medicine, continues to be an important research attempt.…”

“…For energetic materials, halogen is significant in the structural establishment of energetic biocidal agents (iodine based polynitro compounds), solid rocket propellants (ammonium perchlorate, etc) [23] as well as thermally stable energetic materials [1,3,5‐trichloro‐2,4,6‐trinitrobenzene (TCTNB), 1,3,5‐triiodo‐2,4,6‐trinitrobenzene (TITNB), 1,3,5‐tribromo‐2,4,6‐trinitrobenzene (TBTNB), etc] [1], and so on. In recent years, chlorine has been also found in building a series of molecular‐perovskite energetic materials [24–26] and host‐guest explosives with the incorporation of perchlorate ions [27–31]. Therefore, exploring and understanding the relationship between halogen inclusion and physical performance of energetic materials is necessary for the design and development of novel materials towards future advanced applications.…”
