A series of nitro-containing energetic copolymers, HD center dot DNSA (1), G center dot DNSA (2), AG center dot DNBA (3), TZ center dot DNSA (4), 5-ATZ center dot DNSA (5) and 4-ATZ center dot DNSA (6) (DNSA, 3,5-dinitrosalicylic acid; HD, hydrazine; G, guanidine; AG, amino guanidine; TZ, 1H-1,2,4-triazole; 5-ATZ, 5-amino-tetrazole; 4-ATZ, 4-amino-1,2,4-triazole) are successfully synthesized based on intermolecular interactions. All compounds are structurally characterized by powder and single crystal X-ray diffractions, infrared spectrum (IR) and elemental analyses. Thermogravimetric analysis (TG), differential scanning calorimetry (DSC) and density functional theory (DFT) calculations show that compounds 1-6 present favorable thermal stabilities. Moreover, all compounds feature good detonation properties and low sensitivities, representing potential energetic materials and promising alternatives to traditional explosives.
