Abstract
Sulfur-based energetic materials 3 to 7 were synthesized considering the limited availability of structural combinations of polynitrogen and oxygen-based organic scaffolds advancing their limits. All of them were fully characterised using infrared spectroscopy (IR), multinuclear magnetic resonance spectroscopy (NMR), high-resolution mass spectrometry (HRMS), elemental analysis (EA), and differential scanning calorimetry (DSC) studies. Further, the molecular structure of compound 3 was supported using single-crystal X-ray diffraction studies (SC-XRD). All compounds possess good density (1.68- 1.81 g cm-3), moderate detonation performance (VOD= 5747-7075 m s-1; DP= 14.39-19.22 GPa), high thermal stability (159-246 °C) and are insensitive towards impact and friction (IS > 40 J and FS > 360 N) stimuli. This is the first instance of an energetic alliance of pyrazine and thiadiazole frameworks, which can be considered as a developmental step in energetic materials field.
期刊介绍：
Dalton Transactions is a journal for all areas of inorganic chemistry, which encompasses the organometallic, bioinorganic and materials chemistry of the elements, with applications including synthesis, catalysis, energy conversion/storage, electrical devices and medicine. Dalton Transactions welcomes high-quality, original submissions in all of these areas and more, where the advancement of knowledge in inorganic chemistry is significant.
