Abstract :

Heat-resistant explosives are pivotal for specialized applications demanding high thermal stability, essential in both civil and military sectors, especially in extreme environments. Our study focuses on the synthesis of a 3D nitrogen-rich supramolecular energetic metal-organic framework (MOF), Zn(ATZ)2 (1), using the 5-aminotetrazole (HATZ) ligand and Zn(II) ion. Structural analysis indicates that compound 1 adopts the orthorhombic CmCm space group and possesses a robust 2D network, characterized by strong it-it packing interactions between 2D layers, offering exceptional thermal stability up to 322 degrees C with minimal mechanical sensitivity. The standard molar enthalpy of formation ( Delta f H o ) and heat of detonation ( Delta H det ) for compound 1 are calculated to be 7.08 kJ/g and 7.34 kJ/g, respectively. Remarkably, the Delta f H o of compound 1 significantly exceeds those of traditional heat- resistant explosives like RDX (0.32 kJ/g), HNS (0.17 kJ/g), TNT (-0.295 kJ/g), and TATB (-0.54 kJ/g), and is also higher than those of most reported energetic MOF materials. Similarly, its Delta H det value surpasses those of common explosives such as TNT (4.144 kJ/g), HMX (5.525 kJ/g) and RDX (5.71 kJ/g), as well as the majority of reported energetic MOFs. Compound 1 also demonstrates impressive detonation properties with a velocity (D) of 7.22 km s-1 and a pressure (P) of 21.95 GPa, outperforming many other energetic MOF materials. These superior energetic characteristics position compound 1 as a strong candidate for heat-resistant explosives, showcasing its potential for future applications in demanding environments.

Abstract :

Luminescent materials with high thermal stability and significant Stokes shifts are crucial for various applications. In this study, we synthesized a new 3D metal-organic framework (MOF), [Pb-2(dtztp)], using H(4)dtztp (H(4)dtztp = 2, 5-di(2H-tetrazol-5-yl)terephthalic acid) and Pb(II) via hydrothermal synthesis. Single-crystal X-ray diffraction analysis revealed that the Pb2+ ion in the compound exhibits a holo-directed coordination geometry. Each dtztp(4-) ligand connects ten Pb2+ ions through its carboxylate and tetrazole groups, forming a 3D condensed framework. The MOF demonstrates remarkable thermal stability, withstanding temperatures up to 400 degrees C. It emits green light at 508 nm when excited at 312 nm, with a large Stokes shift of 196 nm. In comparison, the free H(4)dtztp ligand emits at 388 nm upon 239 nm excitation, with a Stokes shift of 149 nm. Compared to the free ligand, the MOF shows a significant red shift in fluorescence emission, moving from the UV region of the free ligand to the visible green range. Theoretical calculations suggest that the luminescence of the compound still originates from the ligand, likely due to Pb(II)-induced perturbation of the ligand-centered pi -> pi(*) transition. This study highlights the potential of Pb(II)-organic frameworks with large Stokes shifts as photoluminescent materials for applications in photonics and sensing. The successful synthesis of this MOF not only enriches the chemistry of lead-organic frameworks with large Stokes shifts but also expands the versatility of the H(4)dtztp ligand.

Abstract&Keyword Cite

Abstract :

This study reports the synthesis and characterization of a new 3D Cd(II) metal-organic framework (MOF), [Cd2(BTC)(ATZ)(DMF)(H2O)]H2O, constructed from 1,3,5-benzenetricarboxylic acid (H3BTC) and 5-aminotetrazole (HATZ) ligands via a solvothermal method using a DMF-water solvent system. Single-crystal X-ray diffraction analysis reveals its unprecedented topology, while Hirshfeld surface analysis provides detailed insights into the intermolecular interactions. The compound exhibits intense green photoluminescence at 529 nm upon excitation at 433 nm, which is attributed to ligand-centered pi ->pi* electronic transitions. Compared to free ligands, the emission shows a significant redshift, primarily due to the coordination of DMF molecules and the rigidity of the MOF framework. The study highlights the effectiveness of mixed-ligand strategies and solvothermal synthesis in creating MOFs with tailored properties. This new MOF not only expands the structural diversity of luminescent materials but also shows great potential for applications in light-emitting diodes (LEDs), laser technology, and bioimaging. The findings demonstrate the significant role of solvent systems and ligand combinations in controlling the structural and photoluminescent properties of MOFs, offering valuable guidance for the design and synthesis of advanced functional materials in the future.

Abstract :

Second-order nonlinear optical (NLO) materials have important applications in the realms of photoelectronics and photonics whose microstructures need to be organized into a noncentrosymmetric (NCS) structure. In this work, a mixed-ligands three-dimensional (3D) noncentrosymmetric coordination polymer Zn(OBA)(DIB)center dot 0.5H(2)O (1) was hydrothermally prepared from 4, 4'-oxydibenzoic acid (H(2)OBA), 1, 3-di(1H-imidazol-1-yl)benzene (DIB) and Zn(NO3)(2)center dot 6H(2)O via spontaneous resolution approach, which crystallizes in a noncentrosymmetric space group Fdd2. Compound 1 was characterized by powder X-ray diffraction (XRD), thermogravimetric (TGA) and IR analyses. The structural analysis shows that 1 is a two-fold self-interpenetrated three-dimensional (3D) network material. Single crystal X-ray diffraction and the topological analysis manifests that the topological structure of 1 belongs to a cds topological net. The measurement of the fluorescent properties of 1 and the free DIB ligand show that the emission peak at 460 nm of 1 can be attributed to the charge transition from the. bond electron to the. anti-bond orbital of the DIB ligand. The second-harmonic generation (SHG) measurement shows that the second-order NLO effect of compound 1 is approximately equivalent to that of potassium dihydrogen phosphate (KDP). Compound 1 is high thermal stable and insoluble in water and common organic solvents, making it to be a potential candidate as a second-order NLO material.

Abstract :

A fast-response and highly linear humidity sensor based on quartz crystal microbalance (QCM) was prepared by using polyvinyl alcohol (PVA) and nano-silica composites as sensing film. The mass ratio of PVA to nano-silica and the total mass of sensing film which can significantly influence the response time and linearity of humidity sensor were well discussed. The results show that the optimal mass ratio of PVA to nano-silica is 1:1.5 and the total mass of the sensing film coated on the surface of QCM is 1.0 mu g. Under the optimum conditions, the frequency shifts linearly respond to the relative humidity. The prepared humidity sensor has short response time (5 s), short recovery time (21 s), good stability and reproducibility. The developed humidity sensor is expected to be used for the detection of humidity in practice.

Abstract :

Nitrogen-rich high density metal-organic frameworks (MOFs) can be used as a new type of energetic materials. The energetic MOFs provide a new method to reconcile contradiction between high energy and reliable safety in energetic materials. Framework interpenetration would be an effective approach to reduce the pore volume and meanwhile to enhance the structural/chemical stabilities of the target energetic MOFs. In this work, mixed ligands of 5-aminotetrazole (HATZ) and tetrazole (HTZ) were chosen to assemble with Zn(II) ions with the purpose to prepare interpenetrated MOF materials with insensitivity. Ultimately, a high-density 3D energetic compound, [Zn-2(ATZ)(2)(TZ)(2)](n) (1) was in situ isolated under simple hydrothermal conditions. In the crystal structure of 1, there existed two independent 3D diamond networks, which were formed by Zn1(II) ions/TZ(-) ligands and Zn2(II) ions/ATZ(-) ligands, respectively. These two independent 3D diamond networks were interpenetrated to each other to construct a 3D condensed high-density framework. The standard molar enthalpy of formation (Delta H-f degrees) of 1 was deduced as 1786.45 kJ/mol (4.09 kJ/g), which to date still occupies the status of the top high Delta H-f degrees value among the reported energetic MOF materials. Conducted sensitivity measurements demonstrated the insensitivity of 1 to external mechanical stimuli. TGA showed 1 had good thermal stability up to 332 degrees C, whereas the decomposition temperature of pure HATZ and HTZ ligands are 207 and 174 degrees C, respectively. This shows that the greater stability of 1 could be attributed to the structural reinforcement induced by the effect of coordination polymerization and framework interpenetration. Compound 1 can serve as a promising energetic material with a high level of safety because of its good energetic properties, insensitivity, and high thermal stability.

Abstract :

Viologen bismuthate halides generally show photochromic properties. In the present work, phenylethyl alcohol was introduced into chloro bismuthates in the hope to prepare photochromic crystalline materials and finally a photochromic inorganic-organic hybrid, (PeV)(3)(Bi2Cl9)(2) (1), based on an in situ generated PeV(2+) cation (PeV(2+) = phenethylviologen = N,N '-diphenethyl-4,4 '-bipyridinium), has been obtained, whose microstructure contains a discrete dimer [Bi2Cl9](3-) counterion identified by single crystal X-ray diffraction. More importantly, 1 exhibits a typical photochromic behavior, which can be mainly attributed to the reversible inter-conversion between the monocation viologen radical [PeV](+center dot) and the viologen dication [PeV](2+).

Abstract :

The detection of hypochlorite (ClO-) content in tap water is extremely important because excess amounts of hypochlorite can convert into highly toxic species and inadequate amounts of hypochlorite cannot fully kill bacteria and viruses. Although several metal-organic frameworks (MOFs) have been successfully employed as fluorescent sensors for hypochlorite detection, all these sensors are based on single emission that responds to the dose of hypochlorite. Ratiometric sensors are highly desirable, which can improve the sensitivity, accuracy, and reliability via self-calibration. Herein, a nanoscale dual-emission multivariate 5-5-Eu/BPyDC@MOF-253-NH2 was synthesized by sequential mixed-ligand self-assembly and postsynthesis method. Among the two emission bands of 5-5-Eu/BPyDC@MOF-253-NH2 the strong blue emitting derived from ligands is sensitive to hypochlorite, while the red emitting derived from Eu(III) almost keeps invariable. Therefore, 5-5-Eu/BPyDC@MOF-253-NH2 was exploited as a fluorescent ratiometric nanosensor for "on-off" sensing of hypochlorite. Notably, the proposed sensing system showed an excellent performance including fast response (within 15 s), relative high specificity, wide linear range (0.1-30 mu M), and low detection limit (0.094 mu M). Besides, the suppressed blue emitting was recovered after the addition of ascorbic acid (AA) that consumes ClO- via the redox reaction. Therefore, 5-5-Eu/BPyDC@MOF-253-NH2 was further employed as a fluorescent ratiometric nanosensor for the "on-off-on" sensing of AA. This work represents the first MOF-based fluorescent "switch" for the ratiometric sensing of hypochlorite and the second for ratiometric sensing of AA.

Abstract :

Two new model complexes related to the [FeFe]-hydrogenase active site (mu-SCH2CCCH2Cl)(2)Fe-2(CO)(6) (1) and (mu-SC2H5)(mu-SCH2CCCH2Cl)Fe-2(CO)(6) (2) were obtained by treating (mu-LiS)(2)Fe-2(CO)(6) with 1, 4-dichloro-2-butyne. By controllable CO displacement of 1 or 2 with PPh3, mono- and di-substituted complexes, namely [mu-SCH2CCCH2Cl)(2)Fe-2(CO2)(6-x)(PPh3)(x)] (3, X = 1; 5, X = 2), and [(mu-SC2H5)(mu-SCH2CCCH2Cl)Fe-2(CO)(6-x)(PPh3)(x)] (4, X = 1; 6, X = 2) could be prepared in moderate yields. Treatment of 1 or 2 with bis(diphenylphosphino) ethane (dppe) afforded a double butterfly complex [(mu-SCH2CCCH2Cl)(2)Fe-2(CO)(5)](2) (mu-dppe) (7) and (mu-SC2H5)(mu-SCH2CCCH2Cl)Fe-2(CO)(5)](2) (1-dppe) (8), respectively. These molecular structures were characterized by FT-IR, H-1, P-31 NMR spectra and the molecular structures of complexes 1, 3, 6 and 8 were determined by single crystal X-ray analyses. The electrochemistry of 1-8 was studied and the electrocatalytic property of 1 was investigated for proton reduction in the presence of acetic acid.
