Abstract
The integration of dual asymmetric catalysis is highly beneficial for the synthesis of organic molecules with multiple stereocenters. However, two major issues that need to be addressed are the intrinsic deactivation of dual-species and the extrinsic conflict of reaction conditions. To overcome these concerns, we have utilized the compartmental and thermoresponsive properties of poly(N-isopropylacrylamide) (PNIPAM) to develop a cross-linked PNIPAM-hydrogel-supported bifunctional catalyst. This catalyst is designed with Rh(diene) species situated on the outer surface and Ru(diamine) species positioned within the interior of the hydrogel. The compartmental function of PNIPAM in the middle overcomes intrinsic mutual deactivations between the dual-species. The thermoresponsive nature of PNIPAM allows for precise control of catalytic pathways in resolving external conflicts by controlling the reaction switching between an Rh-catalyzed enantioselective 1,4-addition at 50°C and a Ru-catalyzed asymmetric transfer hydrogenation (ATH) at 25°C. As we envisioned, this sequential 1,4-addition/reduction dual enantioselective cascade reaction achieves a transformation from incompatibility to compatibility, resulting in direct access to γ-substituted cyclic alcohols with dual stereocenters in high yields and enantio/diastereoselectivities. Mechanistic investigation reveals a reversible temperature transition between 50°C and 25°C, ensuring a cascade process comprising a 1,4-addition followed by the ATH process.

Abstract
With the aim to obtain targeted chemotherapeutic agents, imidazolium and ammonium-based folate salts were synthesized. Their photophysical behavior was investigated both in buffer and buffer/DMSO solution as well as in solid phase, performing UV-vis and fluorescence investigations. Properties of the aggregates were also analyzed by dynamic light scattering. Gelation ability of the salts was analyzed in biocompatible solvents, and gel phases obtained were characterized by determining critical gelation concentrations and gel-solution transition temperatures. Insights about gelator interactions in the tridimensional network were also gained performing ATR-FTIR investigation. Properties of soft materials were further analyzed performing rheology measurements, scanning electron microscopy, fluorescence and resonance light scattering investigations. Antiproliferative activity of organic salts was tested towards two breast cancer cell lines, expressing different levels of folate receptor, namely MDA-MB-231 and MCF-7, and a normal epithelial cell line, like h-TER T-RPE-1, by using MTT assay. Dichlodihydrofluorescein acetate test was performed to verify the role of oxidative stress in cell death. Finally, antiproliferative activity was also evaluated in gel phase, to verify if salts were able to retain biological activity also after the entrapment in the gelatinous network. Results collected evidence that folate based organic salts were able to behave as targeted chemotherapeutic agents both in solution and gel phase, showing uptake mechanism and selectivity indexes that depend on both cancer cell line nature and salt structure.

Preparation of Eu(III) Complexes Containing Maleopimaric Acid Anhydride with Ultra-narrow and Efficient Fluorescence Emission for High Determination on Gallic Acid in Acetonitrile Solution. J Fluoresc 2023; 33:223-237.

Abstract
Two novel Eu(III) complexes constructed by maleopimaric acid anhydride (MPA) and 2,2'-bipyridyl (Bpy) / 1, 10-phenanthroline (Phen), named as MPA-Bpy-Eu / MPA-Phen-Eu, have been synthesized by a one-step precipitation method. FTIR, UV, TG, elemental analysis, XPS, and ESI-MS revealed the successful coordination of Eu(III) ions with MPA and Bpy / Phen through Eu-O and Eu-N bonds, respectively. Introducing MPA into coordinate structure increased the electron cloud density in 3d5/2 orbit of Eu(III) ions, enhanced the absolute quantum yields of MPA-Bpy-Eu (89.27%) and MPA-Phen-Eu (94.41%), and decreased the full width at half maxima of 5D0 → 7F2 transitions of MPA-Bpy-Eu (2.23 nm) and MPA-Phen-Eu (2.93 nm), respectively. The fluorescence quenching experiments showed that there was a good linear relationship between the relative fluorescence intensity of MPA-Bpy-Eu and gallic acid (GA) concentration in acetonitrile solution in the range of 0 to 8.41 × 10-2 mM. The results of UV-vis spectra, the fluorescence lifetimes, and the quantum yields demonstrated that the dynamic quenching model played a major role in the quenching process of GA on MPA-Bpy-Eu. The quenching process of GA on MPA-Phen-Eu involved dual fluorescence quenching mechanistic pathways, including static and dynamic models.

Abstract
Sequestration of hazardous radioactive iodine and dye separation to reduce industrial waste through reutilization is pivotal for environmental safety. In this regard, herein, the synthesis of a new waterborne ultrasensitive supramolecular metallogel (Mg@DEOA) with a 2D sheet morphology is accomplished through direct mixing of a low molecular weight gelator diethanolamine and magnesium nitrate hexahydrate. This porous metallogel (180 m2 g-1) exhibits thixotropic properties and is injectable. The material was found to be an effective (587 mg g-1) host matrix for iodine sequestration from solution. Moreover, the Mg@DEOA xerogel was used to efficiently remove rhodamine B from a mixture of dyes with high separation factors through a xerogel packed column and as an adsorbent material for water-soluble dyes and CO. This column based application demonstrated by the metallogel could be useful for practical industrial dye-separation.

Abstract
Materials have been developed that encapsulate a homogeneous catalyst and enable it to operate as a heterogeneous catalyst in water. A hydrophobic ionic liquid within the material was used to dissolve Fe-TAML and keep it from leaching into the aqueous phase. One-pot processes were used to entrap Fe-TAML in basic ionic liquid gels, and ionic liquid gel spheres structured via a modified Stöber synthesis forming SiO2 particles of uniform size. Catalytic activity was demonstrated via the oxidative degradation of dyes. Fe-TAML entrapped in a basic ionic liquid gel exhibited consistent activity in five recycles. This discovery of heterogenized H2O2 activators prepared by sol-gel and Stöber processes opens new possibilities for the creation of engineered catalytic materials for water purification.

Abstract
The title compound 1-octyl-3-(3-(1-methylpyrrolidiniumyl)propyl)imidazolium bis(trifluoromethane)sulfonimide was prepared in three steps. This asymmetrical dicationic ionic liquid (ADIL) is composed of two different positively charged head groups (1-octylimidazolium and methylpyrrolidinium cations), which are linked through a propyl alkyl chain and by two bis(trifluoromethane)sulfonimide anions. The final ADIL was obtained by a simple metathesis reaction of the corresponding dibromide ionic liquid, in turn prepared by alkylation of 3-(3-bromopropyl)-1-propylimidazolium bromide. The ADIL structure and those of its precursors were confirmed through NMR and infrared spectroscopy, and the thermal properties of all compounds were evaluated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Density, solubility, and viscosity were measured for the prepared compounds.
