The good performances of 1,1-diamino-2, 2-dinitroethylene (FOX) have attracted people′s much attention in the field of energetic materials. This paper reviews the latest development of the research works on FOX-7, and the followings concerned are included. (1) Theoretical studies: The detonation velocity, detonation pressure, thermal stability, a number of thermodynamic properties and molecular structural parameters for FOX-7 have been calculated; (2) Synthetic routes: Several synthesis procedures and their modification for FOX-7 are described. At the present time, the preparation of FOX-7 has been scaled-up to 7kg/batch. (3) Properties: Quite a number of properties of FOX-7 have been measured and studied, and the related data are cited in this paper, including density, reactivity, thermal stability, compatibility, sensitivity, detonation parameters etc. It can be concluded that sensitivity of FOX is lower than that of RDX, but its energy level is close to that of RDX. Moreover, FOX is compatible with usual additives used for energetic materials. It is expected that FOX-7 has a good potential applications in insensitive munitions.
