Summary: This study systematically investigates the coherent spin precession, dephasing and relaxation processes of electrons and holes in two hybrid organic-inorganic metal halide perovskites. The results show that these materials exhibit robust spin precession and the spin dephasing and relaxation processes may be influenced by defect levels. Temperature-dependent measurements provide insights into the spin relaxation channels. The extracted electron Land & eacute; g-factors have the largest values reported in inorganic or hybrid perovskites. Both the electron and hole g-factors show significant shifts with temperature, which is proposed to be due to thermal lattice vibration effects on the band structure. These findings lay the groundwork for further design and application of lead- and tin-based perovskites in spintronic devices.

Summary: Ligands with a purely aliphatic backbone have become increasingly important in the chemistry of coordination polymers and metal-organic frameworks. Their unique characteristics, such as increased conformational freedom, non-polarizable core, and low light absorption, provide rare and valuable properties for derived MOFs. These compounds have found extensive applications in stimuli-responsive materials, gas and vapor adsorbents with high selectivity, light-emitting materials, and optical materials. This short critical review summarizes and analyzes the properties of aliphatic-based metal-organic frameworks, as well as reviews the advanced characterization techniques used in this field.

Summary: Hybrid perovskites with mixed organic cations, such as phosphonium and ammonium cations, have rarely been reported due to specific size requirements. In this study, an organic-inorganic hybrid perovskite (Me3PCH2CH2CH3)2(CH3CH2CH2NH3)Sb2Br9 (1) with [Me3PCH2CH2CH3]+ and [CH3CH2CH2NH3]+ cations was synthesized. Compound 1 showed improved phase transition temperature and thermal stability compared to hybrid perovskites with only one type of organic cation. The disorder of [CH3CH2CH2NH3]+ cations and the twisting motion of [Me3PCH2CH2CH3]+ cations and the inorganic skeleton were identified as the main factors for the phase transition of 1 at high temperatures. Furthermore, 1 exhibited semiconductor properties with an optical band gap of 2.945 eV, indicating its potential as a functional perovskite material with mixed organic cations.

Summary: A series of Co(II)-H2L coordination polymers were synthesized with different auxiliary ligands. X-ray diffraction analyses revealed that 1, 3, and 4 have a two-dimensional (2D) structure, while 2 has a one-dimensional (1D) double-chain architecture. Sensing experiments showed that 1 and 2 can selectively detect Cr3+, Al3+, and Pb2+ ions through fluorescence turn-on effect, while 3-4 exhibit fluorescence turn-off sensing behavior for Fe3+ ions. Moreover, 1-4 can effectively detect and recognize Cr2O72- and CrO42- in aqueous solutions.

Summary: The electronic properties of semiconducting inorganic lead sulfide (PbS) nanocrystals and organic linker molecules depend on the size of the nanocrystals and the ligands used. Mixing a weakly binding ligand with a strong binding partner can successfully create coupled organic-inorganic nanostructures. This study demonstrated that using a mixed ligand system improved the film homogeneity, reduced trap density, and enhanced photocurrent of the derived devices, making it a versatile tool for achieving COINs with improved performance.

Summary: Metal-organic frameworks (MOFs) constructed with mixed ligands show great promise in improving materials' properties, with the incorporation of different functionalized ligands within the MOF structure impacting its performance in photocatalytic water reduction. The presence of multiligand incorporation modifies the light absorption spectrum and electronic structure, enhancing the photocatalytic performance and hydrogen evolution rate. Among the tested nanoparticle/MOF photocatalytic systems, the Pt/MIL-125-NH2/(OH)(2) system outperforms its counterpart due to enhanced p-pi conjugation and red-shifted absorption spectrum.

Summary: Lead halide perovskite-based solar cells have shown promising potential for photovoltaic applications due to their low cost, high absorption coefficient, and other intriguing characteristics. However, the toxicity and stability of lead pose challenges, leading to the need for lead-free alternatives. Lead-free mixed organic-inorganic halide perovskites have revolutionized the field and achieved a dramatic increase in power conversion efficiency. These materials are more promising and comparable to silicon-based PV applications, thanks to their efficiency and low-cost processing. This review article focuses on the properties, preparation processes, and various applications of these hybrid mixed halide perovskites, providing an overall performance evaluation from synthesis to multifunctional applications.

Summary: The key to designing and fabricating highly efficient mixed protonic-electronic conductors materials (MPECs) is to integrate the mixed conductive active sites into a single structure, to break through the shortcomings of traditional physical blending. Herein, an MPEC composed of 2D metal-organic layers and hydrogen-bonded inorganic layers was constructed using the assembly methods of layered intercalation based on host-guest interaction. The 2D intercalated materials demonstrated significantly higher proton and electron conductivity compared to pure 2D metal-organic layers, due to the inserted hydrogen-bonded inorganic layers providing the proton source and efficient proton transport, as well as reducing the bandgap and increasing the electron transport of the metal-organic layer.

Summary: Nanocomposites formed by MoS2 nanotubes with P-modified SWCNT and BCNNT through solution-phase flocculation show enhanced photocatalytic and electrocatalytic HER activities. The H2 yield improves with higher proportion of MoS2 nanotubes, with the MoS2-P.SWCNT (3:1) nanocomposite exhibiting the highest H2 evolution rate. Electrostatic stacking of 1D MoS2 nanotubes with SWCNT/BCNNT appears to be an effective strategy for HER and related catalytic reactions.

Summary: The formation of hierarchical porosity in HP HKUST-1 MOFs was investigated using gemini surfactants as soft-templates. The composition of solvent mixtures and reaction parameters played a crucial role in the successful formation of hierarchical porosity. The presence of mesopores in the samples was proven through various characterization techniques, and a direct correlation was found between the hierarchy factor and dye-uptake, suggesting the potential of the hierarchy factor as a quantitative marker for hierarchical porosity.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
