Summary: We report the growth and photophysical characterization of two polar hybrid lead halide phases, methylenedianiline lead iodide and bromide, (MDA)Pb2I6 and (MDA)Pb2Br6, respectively. The noncentrosymmetric crystal structure of these phases leads to highly oriented molecular dipole moments, resulting in second harmonic generation (SHG) upon excitation at 1064 nm. The size dependence of the SHG signal indicates that the bromide exhibits a stronger phase-matching response while the iodide exhibits a significantly weaker non-phase-matching signal. Fluorescence from (MDA)Pb2Br6 is observed around 630 nm below 75 K, whereas (MDA)Pb2I6 exhibits very weak luminescence. The contrasting optical properties are attributed to differences in the character of the halide sublattice, with the increased polarizability of the iodide ions reducing the local electric field in the crystals.

Summary: Organic room-temperature phosphorescence (RTP), especially ultralong organic RTP (UOP), has great potential in fields such as flexible intelligent information encryption, optical anticounterfeiting, and biological imaging. Various strategies have been implemented to improve phosphorescence quantum yield and lifetime, with the confinement effect of inorganic micro/nanostructures being particularly effective. The confinement of inorganic frameworks can enhance the efficiency and lifetime of RTP for organic phosphors, as well as the interactions between organic and inorganic components.

Summary: Chiral and bi/multifunctional catalysts play important roles in sustainable organic transformations. Polyoxometalates (POMs) have great potential in asymmetric and one-pot tandem reactions due to their diverse structures, good redox properties, and oxidation abilities. However, the solubility of POM catalysts in many solvents limits their applications. To overcome this issue, researchers have proposed the combination of POMs with organic units to generate POM-based inorganic-organic hybrid materials with unique structural characteristics, serving as heterogeneous catalysts for asymmetric and one-pot tandem reactions.

Summary: Organic-inorganic metal halide hybrids have great potential for applications in catalysis, solar cells, gas sensing, etc. A novel strategy was developed to improve their gas sensitivity in gas detection by utilizing their highly designable structure. Two new hybrids were synthesized using [(Et)2MP]+ (MP = p-mercaptopyridine, Et = ethyl) as the cationic template, and the sensitivity of gas sensing was enhanced by adjusting the electronic structure through changing the halogen. The difference in response values for NO2 reached 27 times before and after the halogen change. This work provides insights for designing gas-sensing materials with improved properties.

Summary: This review provides an overview of the use and role of coordination complexes as precursors for the generation of hybrid catalysts in oxidation reactions for fine chemical synthesis. The understanding of active site formation in hybrid catalysts is emphasized, and different families of coordination precursors are considered. Each example includes a brief analysis of synthesis, characterization, and catalytic performance. Special attention is given to the chemical environment of the active metal center's first coordination sphere. By integrating advantages of both homogeneous and heterogeneous systems, catalysts obtained through heterogenization, grafting, or anchoring of homogeneous catalysts exhibit enhanced catalytic performance. Deposition of coordination complexes onto preformed supports offers a versatile strategy for designing novel catalysts with tailored and controlled properties.

Summary: Recently, a new method has been developed to produce densified woods with increased density and improved mechanical properties by using less polluting agents. The method involves delignification and densification processes, resulting in a two to four-fold increase in density. Characterization techniques showed a decrease in lignin and a significant increase in density and force necessary to yield. The obtained densified woods can be used as an alternative to other composite woody materials due to their enhanced mechanical properties.

Summary: In this study, the magnetic and relaxation properties of a series of oxovanadium(IV) complexes were investigated. The complexes include [VO(H2O)5]2+, [VO(ox)2]2-, [VO(nta)]-, [VO(dtpa)] 3-, and [VO(acac)2]. The complexes were characterized using EPR measurements and NMRD studies. The results showed differences in the relaxation times and coordination behavior of [VO(acac)2]. The NMRD profiles had contributions from outer- and inner-sphere mechanisms, with the latter including dipolar and scalar mechanisms. The analysis provided information on the exchange rate of coordinated water molecules.

Summary: The Fe(III)-Tiron system was investigated using a combination of experimental and theoretical methods to obtain the speciation in aqueous solution at different pH values. The relaxometric properties of [Fe(Tiron)3]9-, [Fe(Tiron)2(H2O)2]5-, and [Fe(Tiron)(H2O)4]- complexes were characterized using NMR experiments and calculations. The geometry of the Fe3+ coordination environment significantly affects the electronic relaxation, as evidenced by NMR profiles and calculations. Dissociation kinetics studies showed that the [Fe(Tiron)3]9- complex is relatively inert, while the [Fe(Tiron)2(H2O)2]5- complex is more labile.

Summary: This paper discusses the preparation of thermoreversibly crosslinked composite rubbers that are industrially viable and environmentally sustainable. A maleimide-functionalized silica (Sil-M) is used as a reinforcement filler and crosslinking agent on furan-grafted ethylene-propylene rubber (EPRgF) via Diels-Alders reaction. The composite rubbers are prepared by reactive melt blending without using organic solvents. Mechanical properties are compared between EPRgF/Sil-M and unfunctionalized EPRgF/Sil to show the impact of DA crosslinking. The study also investigates the combination of Sil-M and bismaleimide to optimize crosslinking and material performance.

Summary: This article describes nanogels based on a chitosan matrix stabilized by a Mn-t-CDTA bisamide derivative. These nanogels are proposed as an alternative to less stable paramagnetic nanogels obtained by electrostatic interactions. The novel nanogels have improved relaxivity values, high stability, good extravasation and accumulation, and high T-1 contrast in tumors. These properties make them promising MRI probes for in vitro and in vivo preclinical applications.

Summary: For the first time, this study reports the direct incorporation of Sb(V) ions into a polycondensed silsesquioxane network based on heptaisobutyl POSS units. The chemical properties of the Sb-containing POSS compounds were analyzed and it was found that the corner-capping reaction was successful for both samples. The Sb(V)-POSS sample exhibited a heterogeneous multimeric arrangement and an irregular organization of POSS cages linked to Sb(V) centers, indicating a more complex structure compared to the well-defined monomeric Sb(III)-POSS.

Summary: Linear saturated or unsaturated aldehydes were impregnated into synthetic saponite clay using an incipient-wetness deposition method. Cetyltrimethylammonium (CTA(+)) species were added to increase aldehyde loading and enhance the hydrophobic character of the clay. The aldehydes were mainly adsorbed on the surface of the clay particles, with a small fraction inside the interlayer space. In CTA(+)-modified saponites, the concentration of saturated aldehydes was higher compared to pure clay. These findings are promising for the development of novel layered solids containing bioactive molecules for eco-friendly and sustainable crop protection.
