Abstract The hierarchical hollow structure can endow functional materials with concerning performances, whereas its rational design remains challenging, especially for organic molecules. Herein, a novel strategy of self‐template evolution is presented to construct spherulites (HSs) energetic controllable safety and enhanced combustion, utilizing the mechanism pseudomorphic replacement coupled Ostwald ripening. Specifically, thermodynamically metastable β ‐2,4,6,8,10,12‐hexanitro‐2,4,6,8,10,12‐hexaazaisowurtzitane ( ‐CL‐20) as spontaneously evolves into HSs CL‐20‐based inclusion compounds in solution, during which dissolution ‐CL‐20 crystallization are spatiotemporally correlated, enabling preserving spherulitic structure, cavities formed inside via Moreover, conversion rates mediating solvent cause different locations cavities, two cases exhibited. hollow‐core CL‐20‐formic acid exhibit through manipulating micro‐/nanostructures, hollow‐spoke CL‐20‐CO 2 be efficient carrier composite oxidants, enhancing combustion increases 23.2% pressure duration effect, 9.8% peak pressure, 3.3% pressurization rate. This work offers route crystals performance puts insight broad material systems.
