High tension bonds or high-energy bonds are important elements in the formation of disruptive energetic materials， but it"s hard to form and easy to break，. Their construction has always been a difficult problemin the field of chemistry and energetic materials. By using the unique internal space of molecular cages to “assist” the construction of such chemical bonds provides a feasible route for related research， and has been put into practice. This review summarized “confinement effect”， weak interaction， electron transport and other characteristics of molecular cages. It is discussed that it can prevent oxygen oxidation of P₄ and other high-tension materials， stabilize aryl pentazoles and other high active substances， reactants such as NaN₃ to accelerate the reaction， change the reaction path. The roles of molecular cages in these processes， such as “firewall”， “stabilizer”， “accelerator”， “channel remover” and others， were reviewed， which provided references for the preparation of novel energetic compounds such as TdN₄ and the study of controllable energy release . At the same time， it also points out the key direction of future research： design and synthesis of new and efficient molecular cages. developing good characterization methods and means of molecular cage complex. Enhance the composite and release of multi-environment responsive molecular cages and energetic materials.
