Abstract

A series of purine-based fused tetracyclic energetic materials was synthesized. Incorporation of explosophoric groups afforded compounds with high densities (1.82–1.85 g cm –3 ), high positive heats of formation (433.6–709.0 kJ mol –1 ), and good detonation performance (VOD: 8200–8677 m s –1; DP: 27.5–32.2 GPa). Compounds 5, 6, and 9 exhibit moderate to good thermal stability ( T d = 187–207 °C) and low mechanical sensitivity, indicating these materials are promising candidates for HEDMs.
