Summary: The UV/Vis spectra of a hypothetical negative solvatochromic dye were theoretically calculated and compared with experimental data. The study demonstrated the correlation between the absorption energy and molar absorption coefficient as a function of solvent polarity for several derivatives of the dye. However, the approach is only applicable to negative solvatochromism and needs to be complemented by other methods to explain all aspects of solvatochromism.

Summary: In this study, a fast, cheap, and eco-friendly method for amine group protection was developed. It involves the formation of amide bonds using choline chloride as a hydrogen bond acceptor and the starting amine as a hydrogen bond donor through the generation of in situ amine-based deep eutectic solvents. This novel approach avoids the use of toxic solvents, making it a sustainable alternative to classic amine protection procedures.

Summary: The rationalization of the ionic covalent organic framework (iCOF) has been demonstrated to satisfy the requirements of high-performance photothermal materials in light harvesting, light-to-heat conversion, and water activation. A new iCOF STTP was constructed through Schiff base chemistry using a hydrophilic dye molecule as the ionic building block. The integrated dye-related ionic moieties greatly enhance light absorbance and improve the efficiency of solar water evaporation.

Summary: A new strategy for direct access to fully substituted polycyclic imidazolium salts using alpha-enaminones and proline as the reagents is reported. This open-flask operation is a catalyst-, metal-, and Lewis acid-free green process, which does not require an ion-exchange step. It can produce good yields with minimal formation of side products, and is not limited to aryl substituents.

Summary: This study used eco-friendly amine ionic liquids for the extraction of cresols and evaluated their toxicity. The results showed that the amine ionic liquids were nonharmful. The study also investigated the effects of stirring time, mixture ratio, extraction temperature, and initial content on the extraction efficiency. Quantum chemistry calculations revealed that hydrogen bonds were the major driving forces for cresol extraction. The reusability of the amine ionic liquids was also explored.

Summary: The exploration of new materials and devices for the identification and detection of toxic and carcinogenic benzene vapor is of considerable significance. In this study, material and device engineering was used to synthesize a novel vapochromic dye IDTC1 and study its vapochromism in benzene vapor. A long-period fiber grating (LPFG) sensor coated with graphene/IDTC1 was designed and fabricated for quantitative benzene vapor detection, showing a wide dynamic range and high sensitivity. Density functional theory calculation analysis provided insights into the mechanism of benzene-induced vapochromism.

Summary: Deep eutectic solvents (DESs) exhibit significant depressions in melting points and tunable physicochemical properties, but there is still a lack of predictive understanding of their microscopic mechanisms and structure-property relationships. Research on complex hydrogen bonding is crucial for a deeper understanding and development of fundamental frameworks for DESs.

Summary: A liquid-liquid transition (LLT) is a transformation from one liquid to another through a first-order transition, fundamental to understanding the liquid state. While LLT has been reported in some materials, experimental evidence for its existence in many molecular liquids remains controversial. Studying the local order and structural dynamics across an LLT provides unprecedented possibilities for understanding the nature of the liquid state.

Summary: This study presents a novel hybrid inorganic-organic architecture called polyionic nanoclays (PINCs), which are composed of two-dimensional, few nanometer-thick magnesium phyllo(organo)silicate nanosheets with ordered imidazolium functionalities. The PINCs demonstrate high ionic density, exchangeability of counteranions, and the ability to tailor the organic component, showing promising potential in catalysis, ion exchange, energy storage, and other applications. Additionally, the study also reveals the remarkable catalytic activity of gold nanoparticles supported on PINCs, suggesting a major synergistic effect compared to similar nanoparticles suspended in water.

Summary: By changing the concentration of PEG-b-PCL and/or changing the solvent using different ILs, the shape transformation of self-assembled PEG-b-PCL nanostructures can be effectively induced to generate nonspherical polymersomes, such as worm-like aggregates, stomatocytes, nanotubes, large hexagonal and tubular-shaped polymersomes, providing a promising platform for the design of biodegradable soft dynamic systems. These systems can be used in the micro/nano motor field for cancer-targeted delivery, diagnosis and imaging-guided therapy, and controlled release of therapeutic drugs for the treatment of various diseases.
