Summary: Designing fluorescent sensors for selective detection of CN- in aqueous and even solid states is a challenge due to the aggregation-caused quenching (ACQ) effect. The novel fluorescent probe C-1 reported in this paper exhibited orange-red fluorescence with emission peak centered at 597nm in aqueous solution and solid state, making it a selective CN-sensor with sensitivity and detection limit of 5.97 x 10(-4) M-1 and 1.2 mu M respectively. The interactions between C-1 and CN- were confirmed by UV-visible and fluorescent measurements, and the H-1 NMR titration method demonstrated the detection mechanism.

Summary: We developed a novel dual-fluorescence emission and electrometric sensor based on palladium ion-imprinted organosiloxane nanoparticles (Pd-imp@CDs-Pc), which showed two emission peaks at the double excitation wavelengths of 367 and 620 nm. The sensor exhibited selective recognition ability for Pd(II), as indicated by the distinct quenching of carbon dots (CDs) and slight quenching of phthalocyanine (Pc). The sensor also displayed a sensitive electrochemical signal upon interaction with Pd(II), with a higher response compared to the control nanoparticles synthesized in the absence of Pd(II). The sensor was successfully applied for the determination of Pd(II) in tap water and artificial seawater samples.

Summary: The synthesis and photophysical properties of the molecule (E)-N'-(5-bromo-2-hydroxybenzylidene)-4-hydroxybenzohydrazide (BHHB) were investigated using steady state absorption, emission, and time resolved emission spectroscopy. The molecule exhibits excited state intramolecular proton transfer (ESIPT) process with a large Stoke shifted emission. BHHB serves as a selective aluminium ion sensor in the sub-nano molar scale in aqueous solution, with fluorescence enhancement observed only in the presence of Al3+ ions. The BHHB-Al3+ ion complex can penetrate live Hepatocellular Carcinoma (HepG2) cell membranes and enable imaging of the nucleus of live cells using fluorescence confocal microscopy.

Summary: In this study, a versatile and simple platform based on through-space charge transfer (TSCT) polymers was developed, which exhibited full-color-tunable emission and was aided by predictive machine learning models. By introducing electron donor groups containing simple polycyclic aromatic moieties (e.g., pyrene) through one-step copolymerization or end-group functionalization, continuous blue-to-red emission color tuning was easily achieved in solid polymers. Theoretical investigations confirmed the structurally dependent TSCT-induced emission redshifts. Additionally, the TSCT polymers were demonstrated to be a general design platform for solid-state stimuli-responsive materials, exemplified by their application in information encryption with high-contrast photochromic emission.

Summary: In this study, a supramolecular fluorescent sensor for the detection of closantel was developed through a two-step screening process. The sensor exhibited a fast response (<10 s), high sensitivity, and high selectivity, being able to detect closantel residues as low as 0.29 ppm, which is below the maximum residue level set by government. Application of the sensor in commercial drugs, injection fluids, and real edible animal products demonstrated its versatility. This work provides a fluorescence analytical tool for accurate and selective determination of closantel, and has the potential to inspire more sensor designs for food analysis.

Summary: Carprofen (CPF) is a widely used non-steroidal anti-inflammatory drug in livestock, but its residue in the environment poses a significant risk to human health. Hence, there is a need for a convenient analytical method to monitor CPF. In this study, a dual-emissive supramolecular sensor was constructed using bovine serum albumin and an environmentally sensitive dye, enabling rapid, sensitive, and selective fluorescent detection of CPF. This method also demonstrated a unique ratiometric response to CPF, making it suitable for accurate food analysis. To the best of our knowledge, this is the first fluorescent method for fast determination of CPF in food.

Summary: We report a 3D printing approach for high-resolution manufacturing of structurally complex and mechanically strong PEG hydrogels via heat-assisted digital light processing. By using PEG macromonomer melts and post-printing swelling, high-fidelity 3D hydrogels with complex structures were achieved. The use of a dual-macromonomer resin containing a PEG-based macrophotoinitiator enabled the production of all-PEG hydrogel constructs with compressive toughness up to 1.3 MJ m(-3). This study highlights the potential of heat-assisted DLP of PEG photopolymers for hydrogel fabrication, contributing to the development of 3D tissue-like constructs for regenerative medicine.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
