Molecular perovskites are promising practicable energetic materials with easy access and outstanding performances. Herein, we reported the first comparative thermal research on energetic molecular perovskite structures of (C
6 H14 N2 )[NH4 (ClO4 )3 ], (C6 H14 N2 )[Na(ClO4 )3 ], and (C6 H14 ON2 )[NH4 (ClO4 )3 ] through both calculation and experimental methods with different heating rates such as 2, 5, 10, and 20 °C/min. The peak temperature of thermal decompositions of (C6 H14 ON2 )[NH4 (ClO4 )3 ] and (C6 H14 N2 ) [Na(ClO4 )3 ] were 384 and 354 °C at the heating rate of 10 °C/min, which are lower than that of (C6 H14 N2 )[NH4 (ClO4 )3 ] (401 °C). The choice of organic component with larger molecular volume, as well as the replacement of ammonium cation by alkali cation weakened the cubic cage skeletons; meanwhile, corresponding kinetic parameters were calculated with thermokinetics software. The synergistic catalysis thermal decomposition mechanisms of the molecular perovskites were also investigated based on condensed-phase thermolysis/Fourier-transform infrared spectroscopy method and DSC-TG-FTIR-MS quadruple technology at different temperatures.
