Crystals, Год журнала: 2025, Номер 15(6), С. 530 - 530

Опубликована: Июнь 1, 2025

In the pursuit of advancing knowledge energetic materials, we successfully formulated perovskite DAI-X1 with chemical formula (C12H50I6N3Na2O36). Energetic perovskites hold great promise in various applications, including high-energy storage and propulsion systems, due to their unique combination high energy density structural versatility. DAI-X1, particular, has attracted our attention because its potential for optimized performance these areas. We conducted an in-depth investigation into high-pressure stability using situ Raman spectroscopy analysis. possesses a cubic ABX3 structure, notable modifications spectroscopic characteristics were noted within pressure interval 2.5–7.8 GPa, indicating instability under suggesting possible phase transition. Upon release following compression 12.5 spectra exhibit partial reversibility transition, as certain characteristic peaks return original positions while others retain irreversible shifts. This study establishes fundamental understanding investigating responses analogous materials.

In order to meet the needs of social development, increasing research attention has been paid multifunctional molecular-based phase-transition materials. The traditional materials with a single functional property can be transformed into magnificent ones by adding additional properties-for instance photoluminescence and magnetic order- because having two or more properties simultaneously greatly broadens fields their applications. At present, there are very few showing excellent performance, crystal structure design performance optimization still need studied in depth. Herein, we report development organic-inorganic hybrid materials: (MBA)2ZnI4 (1, MBA = 4-methoxybenzylammonium) switchable dielectricity high temperature (Tc 359.55 K), (MBA)2ZnBr4 (2) green luminescence (λexc 314 nm) nonlinear optical (0.75× KDP). A two-dimensional (2D) fingerprint analysis Hirshfeld surface plots revealed significant difference between hydrogen-bonding interaction before phase transition that afterwards. compounds were further verified, from energy band calculations, direct-band-gap semiconductors. conclusion, this work provided viable strategy, involving application chemical modifications, for designing various

In this work, four energetic nitrates, i.e., 4,7-diamino-1H-[1,2,3]triazolo[4,5-d]pyridazin-5-ium nitrate (1), 2,6-diamino-1‑hydroxy-9H-purine-1,7-diium (2), 6-amino-[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-2-ium (3) and 3,6-diamino-[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-2-ium (4), were prepared comprehensively characterized. The X-ray diffraction results indicated that compounds 1–4 had different layered structures with the densities in range of 1.616–1.805 g/cm3. highest density value 1.805 g/cm3 was represented compound 2, which higher than most other nitrates. Moreover, good thermal stabilities, decomposition temperatures ranged 165–181 °C, made them have great potential to further develop. calculated detonation velocities pressures these 7678–8925 m/s, 21.96–32.39 GPa, respectively. greatest velocity pressure observed 3. specific impulses 199.8–244.9 m/s. Notably, 1 near infrared laser (λ = 1064 nm) ignition capacity, first example CHNO based performance.

Two novel energetic anti-perovskite compounds with the chemical formula (N2H5)3X[B12H12] · H2O, where X− is either [NO3]− or [ClO4]−, were successfully synthesized. Both dodecahydro-closo-dodecaborates crystallize orthorhombically in space group Cmc21, exhibiting relatively similar lattice parameters ((N2H5)3[NO3][B12H12] H2O: a = 915.94(5), b 1817.45(9), c 952.67(5) pm, (N2H5)3[ClO4][B12H12] 1040.51(6), 1757.68(9), 942.34(5) pm both for Z 4). Their synthesis involved two-step process: first, Cs2[B12H12] passed through cation exchange column to yield acidic form of dodecahydro-closo-dodecaborate, (H3O)2[B12H12]. This aqueous solution was subsequently neutralized hydrazinium hydroxide and mixed corresponding water-dissolved salt (nitrate perchlorate). Characterization obtained crystals performed by single-crystal X-ray diffraction Raman spectroscopy as well thermal analyses (TG-DTA DSC). The crystal structure determinations revealed that adopt hexagonal structure, distorted presence water molecules. These containing oxidizing oxoanions demonstrate remarkable ability release large amounts energy (almost 2100 J/g) upon decomposition.
