Explosive properties Explosophores

All the terms discussed so far try to classify an explosive from its physical or explosive properties. The classification of explosives from a chemical viewpoint is of course more relevant to this book. Explosives can be classified according to the functionality they contain, and in particularly, the functional groups that impart explosive properties to a compound. Piets (Zh. Obshch. Khim., 1953, 5, 173) divided explosives into the following eight classes depending on the groups they contained each group is known as an explosophore . 

According to Piets the explosive properties of any substance depend upon the presence of definite structural groupings, called explosophores. The auxoploses fortify or modify the explosive properties conferred by the explosophore. Piets... 

The weakest bonds in an explosive will often determine its sensitivity to impact and such bonds are usually present in the explosophoric groups. Steric and electronic factors also play an important role. Unsurprisingly, factors which increase explosive performance usually have a detrimental effect on stability and sensitivity, and so a compromise must be made. As the database of energetic materials and their properties is ever increasing this task becomes... 

Many energetic componnds have been reported where the azido group is in conjunction with another explosophore . This has been a popular approach to new energetic materials. 2-Azidoethyl nitrate, an explosive resembling nitroglycerine (NG) in its properties, was synthesized some time ago from the reaction of 2-chloroethanol with sodium azide followed by G-nitration of the product, 2-azidoethanol, with nitric acid. °...
