Conclusions and Perspectives

As we known, it is attractive and challenging to achieve a fine balance between energy and safety in the field of HEDMs. Therefore, the in-depth study in the design and syntheses of new HEDMs especially for nitrogen-rich polycyclic-based energetic materials is growing in interest among chemical researchers. Up to now, there are four promising routes to modern HEDMs: crystal engineering, constructing energetic metal organic frameworks, designing polynitrogen compounds and forming energetic salts.
