Abstract:
Laser ignition technology offers a safer alternative to conventional methods, yet requires advanced energetic materials with superior laser responsiveness. In this study, a novel cobalt-based energetic MOF Co(PTO)2 was synthesized via a hydrothermal method using a fused-ring PTO ligand. The material demonstrates a high density (2.14 g cm-3), ultra-high thermal stability (Td = 386.8 °C), excellent detonation performance (D = 8502 m s-1, P = 36.0 GPa), and low sensitivity (IS = 50 J, FS > 360 N). Moreover, it exhibits a low laser ignition threshold and rapid combustion response, showcasing the potential as a high-performance energetic material.
