Synthesis and Characterization of New Calixarenes Containing Explosives with High Temperature Stabilities

A few of novel, thermally stable, nitro‐substituted calixanes were successfully synthesized and their spatial configurations also were confirmed. 14,16,34,36,54,56,74,76‐octanitro‐2,4,6,8‐tetraoxa‐1,3,5,7(1,3)‐tetraben‐zenacyclooctaphane (7) as heat‐resistant explosives can be prepared by means of a facile synthetic produced and shows outstanding properties (good thermal stability and high thermal decomposition temperature and energetic performances). It has also been pointed out that the production of compound 7 is very easy on a large scale. All target compounds was characterized by single‐crystal X‐ray diffraction, NMR and elemental analysis, TG and DSC. In this paper, the macrocyclic compounds are introduced into the study as heat‐resistant explosives firstly, which will change the past stagnant situation!
