“…[1][2][3][4] Therefore, the design and synthesis of new HEDMs with high performance properties has been one of the most challenging tasks in this field. For instance, from the original well-known explosives 1,3,4,6-tetranitroglycouril (TNGU, Figure 1, A), 5 hexahydro--1,3,5-trinitro-1,3,5-triazine (RDX) 6 and 1,3,5,7-tetranitro-1,3,5,7--tetraazacyclooctane (HMX) 7 to the present popular explosives 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20), 8 cis-2,4,6,8-tetranitro-1H,5H-2,4,6,8-tetraazabicyclo [3.3.0] octane (Bicycle-HMX), 9 1,1-diamine-2,2-dinitroethene (FOX-7, Figure 1, B), 10 etc., they are all HEDMs with high positive heats of formation (HOFs) and superior detonation performances (D, detonation velocity and P, detonation pressure). However, in most cases, the requirements of high detonation velocity and detonation pressure are often contradictory to their physical properties such as thermal and hydrolytic stability, sensitivity toward heat, shock, friction and electrostatic discharge, positive oxygen balance, environmentally benign decomposition products, low cost and so on.…”
