“…In 2018, we reported the first examples of molecular perovskite energetic crystals, i.e., (H 2 dabco)M(ClO 4 ) 3 (dabco = 1,4diazabicyclo[2.2.2]octane, M = Na + /K + /Rb + /NH 4 + for DAP-1/2/ 3/4), possessing the cubic perovskite structure and overall detonation performances comparable with RDX (cyclotrimethylene trinitramine) or HMX (cyclotetramethylene tetranitramine). By a simple solution self-assembly of oxidizing and reducing components into a perovskite structure, the molecular perovskite energetic crystals have advantages of low cost, adjustable components, and easy scale-up synthesis, and hence have attracted increasing attentions [16][17][18][19][20][21][22][23][24][25]. In particular, as a typical metal-free member, DAP-4 has gained intense interests for its potential as heat-resistant explosive [26][27][28].…”

Epidemics caused by pathogens in recent years have created an urgent need for energetic biocidal agents with the capacity of detonation and releasing bactericides. Herein we present a new type of energetic biocidal agents based on a series of iodine-rich molecular perovskites, (H 2 dabco)M(IO 4 ) 3 (dabco = 1,4-diazabicyclo[2.2.2]octane, M = Na + /K + /Rb + /NH 4 +for DAI-1/2/3/4) and (H 2 dabco)Na(H 4 IO 6 ) 3 (DAI-X1). These compounds possess a cubic perovskite structure, and notably have not only high iodine contents (49-54 wt%), but also high performance in detonation velocity (6.331-6.558 km s −1 ) and detonation pressure (30.69-30.88 GPa). In particular, DAI-4 has a very high iodine content of 54.0 wt% and simultaneously an exceptional detonation velocity up to 6.558 km s −1 . As disclosed by laser scanning confocal microscopy observation and a standard micro-broth dilution method, the detonation products of DAI-4 exhibit a broad-spectrum bactericidal effect against bacteria (E. coli, S. aureus, and P. aeruginosa). The advantages of easy scale-up synthesis, low cost, high detonation performance, and high iodine contents enable these periodate-based molecular perovskites to be highly promising candidates for energetic biocidal agents.

“…Molecular perovskite energetic crystals, with fully “mixed” oxidant components and fuel components at the molecular level, allow rapid explosive reaction and feature a very high thermal stability benefiting from the strong intramolecular covalent bonds and the intercomponent ionic coulomb interactions. − Compared with traditional organic energetic materials, the advantages of a high detonation performance, high thermal stability, and low cost endow the molecular perovskite energetic crystals with promising applications in the field of energetic materials, especially secondary explosives and propellants. − …”

In recent years, molecular perovskite energetic materials have attracted more attention because of their simple synthesis processes, high thermal stabilities, excellent performances, and great significance as a design platform for energetic materials. To explore the possibility of the application of molecular perovskite energetic materials in heat-resistant explosives, four silver(I)-based molecular perovskite energetic compounds, (H2A)[Ag(ClO4)3], where H2A = piperazine-1,4-diium (H2pz2+) for PAP-5, 1-methyl-piperazine-1,4-diium (H2mpz2+) for PAP-M5, homopiperazine-1,4-diium (H2hpz2+) for PAP-H5, and 1,4-diazabicyclo[2.2.2]octane-1,4-diium (H2dabco2+) for DAP-5, were synthesized by a one-pot self-assembly strategy and structurally characterized. The single-crystal structures indicated that PAP-5, PAP-M5, and DAP-5 possess cubic perovskite structures while PAP-H5 possesses a hexagonal perovskite structure. Differential thermal analyses showed that their onset decomposition temperatures are >308.3 °C. For PAP-5 and DAP-5, they have not only exceptional calculated detonation parameters (D values of 8.961 and 8.534 km s–1 and P values of 42.4 and 37.9 GPa, respectively) but also the proper mechanical sensitivity (impact sensitivities of ≤10 J for PAP-5 and 3 J for DAP-5 and friction sensitivities of ≤5N for both PAP-5 and DAP-5) and thus are of interest as potential heat-resistant primary explosive components.

In this work, we report the thermal kinetics, thermodynamics, and decomposition mechanism of AP-based molecular perovskite energetic materials and estimate their thermal safety performance. Typical AP-based molecular perovskite energetic materials, (H2dabco)[NH4(ClO4)3] (DAP-4), (H2pz)[NH4(ClO4)3](PAP-4), (H2mpz)[NH4(ClO4)3](PAP-M4), and (H2hpz)[NH4(ClO4)3] (PAP-H4), were synthesized and characterized. These were studied using differential scanning calorimetry (DSC). The results show that all of the obtained AP-based molecular perovskite energetic materials have higher thermal decomposition temperatures, and the peak temperatures are more than 360 °C. All follow random nucleation and growth models. Other thermodynamic parameters, such as the reaction enthalpy (ΔH), entropy change (ΔS), and Gibbs free energy (ΔG), show that they are generally thermodynamically stable. Moreover, their adiabatic induced temperatures were obtained; TD24 of DAP-4, PAP-4, PAP-M4, and PAP-H4 were 246.6, 201.2, 194.5, and 217.5 °C, respectively. This study offers an important and in-depth understanding of the thermal decomposition characteristics of AP-based molecular perovskite energetic materials and their potential applications.
