The back cover picture shows the molecular structure of melt‐cast energetic salt diaminoguanidinium N,N′‐dinitro‐N,N′‐bis(3‐dinitromethyl‐furazanate‐4‐yl) methylenediamine (Center). This new energetic salt absorbs the melting characteristics of 3‐(4‐aminofurazan‐3‐yl)‐4‐(4‐nitrofurazan‐3‐yl) (ANTF) (Top right) and 2,4‐bis(2‐nitrazaprop‐1‐yl)‐3‐nitro‐1,2,4‐triazol‐5‐one (Bottom left), which looks just like two DNA helixs of energetic molecules colliding and finishing genetic recombination of a new energetic compound (Molecular background). This new salt exhibits excellent thermal stability (onset m.p. 113 °C, onset dec. 282 °C) which is superior to those of RDX and approach those of TNT. Different from RDX, 5 exhibits better impact and friction sensitivity ( IS : 20 J, FS : 128 N). Worth noting that, its theoretical detonation velocity of 5 ( D : 8500 m s −1 ) is comparable with that of RDX. The above‐mentioned performance indicate that this novel energetic salt could be potentially high‐performance energetic material towards civil and military applications (Center background). More details are discussed in the article by G. Fan et al. on page 90 ff.
