Host-guest energetic nanocomposites have been synthesized by self-assembly of the high energy density compound HNIW in nanometer-scale channels of an ordered mesoporous material SBA-15. The complete impregnation of HNIW can be achieved in acetone solvent at ambient temperature, and the maximum amount was around 70 wt%. Structural characterizations were systematically provided by XRD, TEM, N(2) adsorption, TG, (13)C solid-state NMR and FT-IR. The tendency of multi-nitro organic molecules to self-assemble when the solvent evaporated has been described. Hydrogen bond interactions were considered as the main driving force, so the choices of matched host matrix and guest organic compounds were pivotal for implementing this process. The thermal properties of nanocomposites were measured by DSC analysis. Compared with pure HNIW and a physical mixture, the decomposition peak temperature of the confined crystals decreased about 11?°C, while the total amount of heat released slightly increased. This strategy can also be expanded to other similar host-guest systems.
