Purine-Based Fused Tetracyclic Energetic Materials with Balanced Energetic Performance
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<sup>-3</sup>), high positive heats of formation (433.6-709.0 kJ mol<sup>-1</sup>), and good detonation performance (VOD: 8200-8677 m s<sup>-1</sup>; DP: 27.5-32.2 GPa). Compounds <b>5</b>, <b>6</b>, and <b>9</b> exhibit moderate to good thermal stability (<i>T</i><sub>d</sub> = 187-207 °C) and low mechanical sensitivity, indicating these materials are promising candidates for HEDMs.
