Recently, the utilization of metal halide perovskites in sensing and their application in environmental studies have reached a new height. Among the different metal halide perovskites, cesium lead halide perovskites (CsPbX3; X = Cl, Br, and I) and composites have attracted great interest in sensing applications owing to their exceptional optoelectronic properties. Most CsPbX3 nanostructures and composites possess great structural stability, luminescence, and electrical properties for developing distinct optical and photonic devices. When exposed to light, heat, and water, CsPbX3 and composites can display stable sensing utilities. Many CsPbX3 and composites have been reported as probes in the detection of diverse analytes, such as metal ions, anions, important chemical species, humidity, temperature, radiation photodetection, and so forth. So far, the sensing studies of metal halide perovskites covering all metallic and organic–inorganic perovskites have already been reviewed in many studies. Nevertheless, a detailed review of the sensing utilities of CsPbX3 and composites could be helpful for researchers who are looking for innovative designs using these nanomaterials. Herein, we deliver a thorough review of the sensing utilities of CsPbX3 and composites, in the quantitation of metal ions, anions, chemicals, explosives, bioanalytes, pesticides, fungicides, cellular imaging, volatile organic compounds (VOCs), toxic gases, humidity, temperature, radiation, and photodetection. Furthermore, this review also covers the synthetic pathways, design requirements, advantages, limitations, and future directions for this material.

ABSTRACTOxidovanadium meso‐tetrakis(3,4,5‐trimethoxyphenyl) porphyrin [VO(T(OMe)3PP)] (Complex 1) was prepared. The oxidation product of Complex 1 has been characterized by cyclic voltammetry (CV), UV–visible spectrophotometer, electron paramagnetic resonance (EPR) and nuclear magnetic resonance (NMR) by the addition of SbCl5 to Complex 1. There is a one‐electron oxidation product in Complex 1 that creates π–cation radicals in CV data. This is supported by an IR spectrophotometer. Subsequent EPR spectra verified the initiation of the π–cation monoradical, which subsequently transforms into a triplet state where S = 1. DNA binding and antibacterial analysis with Complex 1 have also been analysed. In the DNA‐binding analysis, the CV data confirm the interaction between Complex 1 and DNA. Furthermore, the fact that Complex 1 is more effective at killing bacteria shows that the metal ion's chelation with the porphyrin ligand makes it more lipophilic.

The potential energy surface (PES) of the oxidative pathways and unimolecular decomposition of CH3CH2C(O)OCH2CH2O radical formed from ethyl propionate has been investigated in details using ab initio density functional method. In present study, it is revealed that five major decomposition pathways with their kinetic and thermodynamics parameters. The geometries of reactants, transition states and product radicals were optimized using the model DFT method M06-2X along with the 6-31+G(d,p) basis set. The mechanistic, kinetic and thermochemical analysis was carried out at the M06-2X/aug-cc-pVTZ//M06-2X/6-311++G(d,p) level. Based on present results, it can be concluded that the oxidative pathway is the most significant for decomposition of CH3CH2C(O)OCH2CH2O radical. The rate coefficients for each reaction channels were determined in a wide range of temperature 250-450 K.

In this work, meso-tetrakis(p-Hydroxyphenyl) porphyrin [T(p-OH)PP] and manganese(III) meso-tetrakis(p-hydroxyphenyl) porphyrin Mn[T(p-OH)PP] were synthesized and characterized. The UV-visible and cyclic voltammetry were used to evaluate the axial ligand and redox behaviour of Mn[T(p-OH)PP]. The addition of ethylamine, diethylamine and tertiary amines to Mn(III) meso-porphyrins distinguishes their axial ligand characteristics. The presence of ethylamine causes the octahedral geometry to transform into a square pyramidal structure. Cyclic voltammetry shows that Mn(III) converts to Mn(II) porphyrins. Additionally, the UV-visible spectrophotometry and cyclic voltammetry were also used to investigate the oxidation process.

A porphyrin compound manganese(III) meso-5,10,15,20-tetrakis(4-pyridyl)porphyrin, Mn(Py)4P containing manganese(III) and 4-pyridyl ligands was synthesized. The UV-visible spectrophotometry and cyclic voltammetry were used to investigate the axial ligand and the redox behaviours of Mn(Py)4P. This study investigates the reduction properties of Mn(Py)4P using primary amine, imidazole and 2-methylimidazole as axial ligands. Reduction of Mn(Py)4P leads to a shift in absorption bands, indicating the conversion from manganese(III) to manganese(II) porphyrin. The addition of primary amine results in a square pyramidal structure for Mn(II) porphyrin, while imidazole or 2-methylimidazole leads to the formation of tetragonal complexes. These changes in geometry result in a decrease in π-bonding. The observed spectral patterns support the involvement of axial ligands in the 5th and 6th positions of manganese(III) porphyrin. The cyclic voltammogram confirmed the alteration in geometry, indicating changes in the redox properties of compound. As a whole, the results of this study provide light on the ways where the behaviour of in which Mn(Py)4P can be altered by the presence of other molecules.

ABSTRACT A quantum chemical study has been presented on the decomposition of CH3CH2C(O)OCH(O • )CH3 which is derived from ethyl propionate (CH3CH2C(O)OCH2CH3) using the M06-2X/6-31 + G(d,p) level of theory. The thermal decomposition of CH3CH2C(O)OCH(O • )CH3 is essential to understand the chemistry of combustion of ethyl propionate. Here, the decomposition and oxidative pathways, bond fission and alpha ester rearrangement of CH3CH2C(O)OCH(O • )CH3 have been explored. We have obtained transition states for the different pathways and further verified each transition state by performing intrinsic reaction coordinate (IRC) calculations. The density of state spectra (DOS) was calculated using GaussSum software. The single-point energy calculations are performed at the same function but using larger basis sets such as 6-311++G(d,p) and 6-311++G(3df,2p). We have shown all stationary points and transition states involved in reaction pathways on the potential energy surface (PES) diagram and also discussed the thermochemistry of each reaction pathway. The thermal rate constants of various channels in the decomposition of CH3CH2C(O)OCH(O • )CH3 are determined using the Conventional Transition State Theory (CTST) in the temperature range of 250–450 K and 1atm. From PES, thermochemistry and kinetics analysis, we found that α-ester rearrangement produces propionic acid, which is dominant over the oxidative pathway for the decomposition of CH3CH2C(O)OCH(O • )CH3.

A natural lignocellulosic fiber has been extracted from Borassus flabellifer leaf sheath (BFSE) fibers and they characterized for its chemical composition, morphology, crystallinity, density, single fiber tensile strength and thermal property through standard analytical method using Fourier-transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD), pycnometer, universal testing machine and thermogravimetric analysis (TGA). The chemical compositions of BFSF were found as cellulose, hemicellulose and lignin contents of 48.20 ± 0.95, 25.92 ± 0.83 and 23.83 ± 0.34%, respectively. The SEM micrograph confirmed the presence of textured surface of fiber. TGA indicates that the fibers are thermally stable up to 208 ºC. The crystallinity and single fiber tensile strength were calculated as 33.15% and 170-220 MPa, respectively.

Meso-5,10,15,20-Tetrakis(o-nitrophenyl)porphyrin, [T (o-NO2)PP] and manganese (III) meso-5,10,15,20- Tetrakis(2,5-dimethoxyphenyl)porphyrin, Mn[T(o- NO2)PP] have been prepared. The Mn[T(o-NO2)PP] complex is characterized by UV-Vis spectrophotometric and cyclic voltametric (CV) studies. The preparation of Mn(III) porphyrin complex may be attributed due to a significant metal-porphyrin π interaction. In Mn(III) porphyrin, Mn is in a high spin d4 configuration with octahedral geometry. Mn(III) porphyrin geometry has been altered to square pyramidal Mn(II) porphyrin after addition of ethylamine. In square pyramidal Mn(II) porphyrin, Mn atom is in a high-spin d5 configuration with the occupied d(x 2 - y 2 ) orbital whose orbital energy is low. This shows that Mn(III) will be out of the plane of porphyrin. Successive addition of diethylamine, Mn(III) porphyrin geometry has been changed to tetragonal complex due to a weak π back bonding. It appears that π -bonding is lowered when the tetragonal complexes are formed. This might arise due to the expansion of the in-plane metal to porphyrin in a direction to occupy two axial ligands of ethylamine. The geometry changes indicate that the two ethyl amines groups occupy 5th and 6th places as axial coordination site due to the availability of two ethylamine from ethyl, diethyl and triethyl amines. Cyclic voltammogram confirmed the oxidation state and reduction behavior of Mn porphyrin complex.

Solution combustion was employed to create a series of ZrO2:Dy3+ (1-11 mol percent) nanoparticles (NPs) using oxalyl dihydrazide (ODH) as the fuel. ZrO2:Dy3+ NPs were subjected to calcination at about 700°C. ZrO2:Dy3+ NPs comprised of 1 to 11 mol% of Dy3+ were characterized by employing the X-ray diffraction (XRD), transmission electron microscopic (TEM), UV-visible, and X-ray photoelectron spectroscopic (XPS) techniques. The crystallite diameters of 1 to 11 mol% ZrO2:Dy3+ NPs were observed to range from 8.1 nm to 16.3 nm, exhibiting spherical shape. According to BET tests, the pore volume of ZrO2:Dy3+ NPs was determined to be 100.129 cm3/g. The mean pore diameter of ZrO2:Dy3+ NPs was determined to be 4.803 nm from the Barrett-Joyner-Halenda (BJH) plot. The photoluminescence and photocatalytic dye degradation properties of ZrO2:Dy3+ NPs were investigated. The acid red 88 (AR88) dye was applied to appraise the photocatalytic activities of the NPs under UV irradiation. ZrO2:Dy3+ NPs with 3 mol% Dy3+ exhibited improvised photocatalytic activity due to the operative departure of charge carriers. The electrochemical examination of ZrO2:Dy3+ NP modified carbon paste electrode in 0.1 N HCl demonstrated considerable redox potential output, as evidenced by cyclic voltammetric and amperometric measurements. The electrochemical sensor studies on ZrO2:Dy3+ NPs exhibited potentiality towards sensing of highly toxic metals like mercury and lead.

The oxidation products of transition metal complexes with porphyrin are being examined currently by many research groups. meso- 5,10,15,20-tetrakis(2,5-Dimethoxyphenyl)porphyrin [T(2,5-(OCH3)2)PP] and its coordination compound with oxovanadium(IV) resulting in VO[T(2,5-(OCH3)2)PP] were prepared by the standard procedures. The resulting complex was characterized with or without the addition of antimony pentachloride by infrared (IR) spectroscopy, electron paramagnetic resonance (EPR) spectroscopy and cyclic voltammetry (CV). The UV-visible absorption spectrum of porphyrin ligand-based oxidation of vanadyl porphyrin VO[T(2,5-(OCH3)2)PP] in the presence of 0.5 mM SbCl5 has shown bands at 425, 540 and 650 nm. The final electro-oxidation product has a broad absorption band centered at 650 nm. It is characteristic of a porphyrin mono- cation which is seen due to oxidation at 0.0995V of ΔE value in the cyclic voltammogram of VO[T(2,5-(OCH3)2)PP]. These spectral features observed during the oxidation are in good agreement with the stepwise formation of mono-cation radical and di-cation. The EPR spectrum of VO[T(2,5-(OCH3)2)PP] suggests that it could be oxidized to the radical cation by oxidation with SbCl5 in dichloromethane. A radical cation is observed at low temperature and this spectrum corresponds to monomeric π-cation radical. A spectrum of fifteen lines is observed on the further addition of SbCl5 in dichloromethane. Thus, monomeric π-cation radical is recognized as [VO(TPP)]+. It is confirmed by the appearance of a new band at 1275 cm-1 in the IR spectrum. Zero field splitting (ZFS) was calculated from the triplet state on the EPR spectrum. It is suggested that ZFS interaction occurs from the dipolar coupling between the two electrons. Keywords: meso-Vanadyl porphyri
