From the standpoint of chemical structures, organic backbones energetic materials can be classified into aromatic rings, nonaromatic and open chains. Although category compounds exhibits several advantages in regulation properties, heterocycles, assembling nitramino explosophores with simple alkyl bridges, still have prevailed benchmark materials. The methylene bridge plays a pivotal role constructions classic heterocycle-based compounds, e.g., hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), whereas ethylene is core moiety state-of-the-art explosive 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20).

Oxadiazole and triazole are extensively investigated heterocyclic scaffolds in the development of energetic materials. New molecules were designed by replacing 1,2,5-oxadiazole with 2H-1,2,3-triazole reported conjugated macrocyclic systems to assess influence on properties stability. In addition, nitro groups introduced units (N-functionalization) improve performance. Energetic properties, including heat formation, oxygen balance, density, detonation pressure velocity, impact sensitivity, estimated for these triazole-based macrocycles. The replacement 2-nitro-1,2,3-triazole significantly enhances energy content, performance, noncovalent interactions. theoretically computed macrocycles reveal high positive heats formation (1507–2761 kJ/mol), balance (−88.8 −22.8%), densities (1.87–1.90 g/cm3), superior velocities (8.41–9.52 km/s), pressures (26.64–40.55 GPa), acceptable sensitivity (27–40 cm), safety factor (51–290). overall assessment highlights as a potential framework that will be useful developing advanced
