Summary: We developed a rational approach for the development of stimuli-responsive ionogels with precise control over their features for pharmaceutical applications. By strategically integrating silk fibroin and biocompatible ionic liquids, we overcame the limitations of complex chemistry, high viscosity, poor biocompatibility, and low biodegradability. Our approach resulted in the formation of thermoresponsive ionogels with tunable properties and enhanced drug solubility. The development of these ionogels has significant implications for drug delivery applications.

Summary: We introduced a new approach for continuous-flow allylic alkylation of N-nucleophiles using Pd-complex-containing supported ionic liquid phases (SILPs). This immobilization strategy provided easy access to catalyst frameworks tolerant to air, allowing rapid and convenient synthesis of various achiral and chiral N-allylation products. The optimized conditions allowed for a 3.5-hour flow-reaction with constant product output, while showing minimal leaching of the ionic liquid (0.7 wt %) and no detectable leaching of palladium-complex.

Summary: The solid network structure of polyvinyl alcohol (PVA) hydrogel has been engineered by introducing ionic liquids (IL), leading to improved ionic conductivity, thermoelectric properties, and mechanical properties of PVA/IL ionogels. The microstructure and ion transport ability of PVA/IL ionogels contribute to the enhanced ionic conductivity. Moreover, the microcrystalline regions and nanoscale network structure in PVA/IL ionogels dissipate a large amount of energy and give rise to excellent mechanical properties, expanding the application potential of ionogels.

Summary: The incorporation of ionic liquids (ILs) in solid-state polymer electrolytes (iono-SPEs) greatly enhances Li+ transport in polymer phases. By using a poly (vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene) (PTC) as the framework of ILs, non-uniform Li+ transport among different phases is reduced. This is achieved through weaker adsorption energy of IL cations on PTC chains compared to PVDF and the higher dielectric constant of PTC facilitating the dissociation of Li-anions clusters. The LiFePO4/PTC iono-SPE/Li cells show stable cycling performance with high capacity retention after 1000 cycles at 1 C and 25 degrees C. This work provides a novel approach to induce uniform Li+ flux in iono-SPEs through polarity and dielectric design of the polymer matrix.

Summary: A cyclometallated rhodium complex was used as a catalyst for the quantitative nucleophilic fluorination of a range of acyl chlorides to acyl fluorides. The catalyst showed high yields and could be separated, regenerated, and reused. The reaction mechanism was proposed to involve a nucleophilic Rh-F bond based on graphical kinetic analysis and DFT calculations.

Summary: An entrapment method for enzyme immobilization without the formation of new covalent bonds is reported. Ionic liquid supramolecular gels containing enzymes can be made into gel beads and used as recyclable immobilized biocatalysts. The gel, formed from a hydrophobic phosphonium ionic liquid and a low molecular weight gelator derived from phenylalanine, allows for 10 runs of recycling without activity loss and retains activity for at least 150 days. No covalent bonds are formed during gel formation, which is supramolecular, and there are no bonds between the enzyme and the solid support.

Summary: Entrapment immobilization involves trapping an active species, often a catalyst, within a material forming a solid or gel. It is used to immobilize enzymes and for whole cell biocatalysis. Despite its advantages of no formal interaction with the protein needed, entrapping isolated enzymes has lagged behind other methods like covalent attachment and crosslinking due to risks of enzyme leaching and mass transfer limitations. Key methods are characterized and recent innovations are highlighted.
