Summary: Supramolecular hydrogels have attracted significant attention due to their versatile approaches for preparation and new facile characterization strategies. In this study, we successfully formed a biocompatible and low-cost supramolecular hydrogel by binding modified cellulose nanowhiskers with gallic acid pendant groups (CNW-GA) with CNW grafted with beta-Cyclodextrin (CNW-g-beta-CD) through HG interaction. We also developed a simple colorimetric characterization method using phenolphthalein (PP) as a visual indicator for confirming HG complexation.

Summary: Cyclodextrin-based fluorescent probes have shown great potential in chemical or biological sensing. In this study, a new probe was developed by linking DASP and B-cyclodextrin. It was found that the intermolecular inclusion complex formed by the probe would disassemble in the presence of amantadine, leading to a decrease in fluorescence intensity. This discovery provides a rapid and selective method for the detection of amantadine and suggests the potential for designing other cyclodextrin-based sensing strategies.

Summary: The thermodynamic parameters of host-guest binding can be used to describe, understand, and predict molecular recognition events in aqueous systems. This study focuses on the contributions of water to binding by studying binding thermodynamics for a series of host-guest systems. It is found that the enthalpic driving forces for binding increase at higher temperatures, and heat capacity changes appear to be a general feature of host-guest complex formation in water.

Summary: In this study, the regulatory mechanism of 8-cyclodextrin (8-CD) on the bactericidal performance and skin irritation of commercial cationic surfactants (CSAa) with different properties was investigated. It was found that when the ratio of 8-CD was not greater than 1:1, the bactericidal efficiency of CSAa@8-CD (n > 12) remained high. However, when the ratio of 8-CD exceeded 1:1, the antibacterial performance decreased due to the interaction between 8-CD and bacteria.

Summary: Biological channels in cell membranes are critical for signal transduction and transmembrane transport regulation. Researchers are developing biomimetic nanochannels to imitate these processes. Unlike fragile biological channels, solid nanochannels have gained interest for their controllable surface chemistry and superior mechanical properties. Surface functionalization with macrocyclic hosts enhances the properties of solid nanochannels, such as stimuli response and separation capabilities. This review summarizes recent advances in nanochannel membranes decorated with macrocyclic host-guest chemistry, covering various responsive nanochannels and separation applications.

Summary: This study develops and investigates a functional nanocomposite hydrogel using cellulose nanocrystals as a biobased filler, and designs the hydrogel by introducing supramolecular bonding between beta-cyclodextrin and adamantane groups at the interface between cellulose nanocrystals and the polymer matrix. The modified cellulose nanocrystals exhibit good dispersibility in aqueous media, even after modification with the hydrophobic adamantane group, due to electrostatic repulsion among negative charges on the nanocrystal surface. The modification also improves the interfacial compatibility between the filler and the matrix, enhancing the toughness of the hydrogel.

Summary: This study investigates the supramolecular recognition behavior of protonated and neutral forms of the acridine orange dye with gamma-cyclodextrin host. The protonated form shows sequential multi-mode binding interactions with the host, forming dimeric inclusion complexes at lower host concentration and monomeric complexes at higher concentration. On the other hand, the neutral form primarily forms dimeric complexes throughout the entire host concentration range. The study provides insights into the pH-dependent interaction mechanism and potential applications in pH-controlled supramolecular assemblies.

Summary: This study investigates the modulation of photophysical and prototropic properties of the BDZ dye by the sulfobutylether-beta-cyclodextrin (SBE beta CD) host. The SBE beta CD host demonstrates different binding strengths for the protonated and unprotonated forms of the BDZ dye, resulting in a significant upward pKa shift. Furthermore, the dye's structure is constrained upon binding with the host, leading to a substantial enhancement in fluorescence intensity and lifetime, as well as an increase in fluorescence anisotropy decay times, confirming the binding between the dye and host.

Summary: This study successfully synthesized various types of thiolated-graphene quantum dots (GQDs) and utilized them in a one-droplet microfluidic paper-based analytical device for the simultaneous multi-sensing of heavy metal ions. The GQDs were functionalized and stabilized on the surface of hydrophobic fiber-glass, enabling colorimetric chemosensing of ions including iron, copper, cobalt, mercury, chrome, manganese, and nickel. The results were confirmed using fluorescence spectrometry, and the platform showed potential for facile metal ion detection in human urine models and environmental fluids.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
