N2 - Recently, significant interest has been directed towards advanced energetic materials due to their high energetic performance with good stability. Achieving a balance between energy and safety using conventional approaches poses a significant challenge. This study employs a promising method for synthesizing thermally stable, insensitive complexes via hydrogen-bonded self-assembly. A vast network of hydrogen bonds is formed between the purine a naturally occurring, readily available compound and picric acid. A series of advanced thermally stable energetic materials (1–3) with a balanced relationship between energy and sensitivity were synthesized through a one-pot, one-step reaction. Notably, these newly synthesized complexes possess a remarkably improved density (1.75–1.79 g·cm−3), better than traditional explosives such as TNT (2-methyl-1,3,5-trinitrobenzene), HNS (1,1′-[(E)-ethane-1,2-diyl]bis(2,4,6-trinitrobenzene)), and PYX (2,6-bis(picrylamino)-3,5-dinitropyridine), while showing insensitivity to impact and friction. These complexes demonstrate that hydrogen-bonded self-assembly is a simple and effective approach for developing advanced heat-resistant explosives with good energy and safety characteristics. This work also highlights hydrogen-bonded self-assembly as a straightforward and effective strategy for designing next-generation heat-resistant energetic materials using naturally occurring compounds.
