Summary: Developing a highly selective and sensitive sensor for Cu2+ ions is of great importance in the fields of chemical, biological, and environmental research. In this study, a novel Cu(2+) ions sensor based on a tetraphenylethylene (TPE) derivative with aggregation-induced emission (AIE) property was designed and synthesized. The sensor demonstrated a sensitive fluorescent turn-off behavior and highly selective responses to Cu(2+) ions, while being unaffected by various interferential cations. Additionally, a visible color change from bright yellow to colorless was observed upon the addition of Cu(2+) ions.

Summary: A highly selective and sensitive fluorescent sensor based on rhodamine fluorophore was developed for detecting Cu2+. The sensor displayed a strong fluorescence turn-on effect upon addition of Cu2+ and could be recognized by the naked eye. The sensor also enabled quantitative analysis of Cu2+ due to the formation of a stable 1:1 metal-ligand complex in a short time, which exhibited good pH stability. Furthermore, molecular orbital and spatial structure investigations, as well as cell imaging and zebra fish experiments, demonstrated the broader application prospects in biological systems.

Summary: In this study, a novel coumarin derivative-modified cellulose acetate (DCB-CA) was synthesized as a fluorescent probe for the highly selective and sensitive determination of CN- in food samples. Different characterization methods were used to analyze the DCB-CA, and it showed a significant fluorescence response to CN- with a distinct color change. The detection limit of CN- using DCB-CA was much lower than the recommended threshold limit by the World Health Organization. The favorable solubility and processability of CA allowed for the easy fabrication of different fluorescent materials, including films and coatings, for CN- detection.

Summary: A Turn-Off fluorescent probe DPAP was successfully developed for the specific detection of Cu2+, which has a large Stokes shift, fast reaction speed, low detection limit, low toxicity, and good cell permeability. Cu2+ quenches the fluorescence of DPAP by blocking its intra-molecular charge transfer process. The application potential of DPAP was demonstrated by successfully detecting Cu2+ in environmental water samples and observing the distribution and translocation patterns of exogenous Cu2+ in HeLa cells and zebrafish.

Summary: Photons with orbital angular momentum exhibit a helical motion and create a light ring. By introducing a perpendicular force during this motion, an additional radial angular momentum is generated, resulting in alternate dark spots on the light ring. Through the hierarchical assembly of helical organic nanowires, a third centrifugal angular momentum is added, reaching the theoretical limit for a photon. This extra angular momentum transforms the dimensionless photon into a hollow spherical photon condensate with interactive dark regions, enabling it to behave like a wave or matter, similar to electrons.

Summary: This study reveals an increase in ferroptosis and a downregulation of Elabela expression in preeclampsia placentas. A mouse model of preeclampsia-like features confirms the presence of a ferroptosis phenotype in the placenta, and Elabela can reduce ferroptosis and improve adverse pregnancy outcomes. Mechanistic studies suggest that Elabela inhibits the ferritinophagy pathway to increase FTH1 levels, chelate intracellular labile iron, and arrest ferroptosis. In conclusion, targeting the Elabela-ferritinophagy-ferroptosis signaling axis provides a new therapeutic intervention strategy for alleviating preeclampsia.

Summary: The researchers reported that a non-planar saddle-shaped N-heterocycle-fused metallo-porphyrinoid can directly form a persistent microporous crystalline material from solution, which can undergo solvent exchange without loss of microporosity. The material is formed by a unique accumulation of intermolecular interactions involving pi-pi stacking of the fused heterocycle, coordinative interactions at the metalloporphyrinoid unit, and hydrogen bonding. This intermolecular multipoint interaction concept will be key in the future molecular design for on-demand synthesis of porous materials, and the simple implementation of the compound described here indicates the excellent potential for device materials' synthesis. Sensing properties of the material incorporated into a nanomechanical sensor array are also reported.

Summary: The discrimination and quantification of aldehydes are difficult due to their similar chemical reactivities. By manipulating the reaction pH, the reactivity of aldehydes and the stability of the resulting Schiffbase can be controlled for analytical purposes. A fluorescent molecule, BS1, with an amino group at the ortho-position, showed significant fluorescence response to formaldehyde at a specific pH, while BS2 and BS3 showed negligible responses. A pH-mediated sensor array, BS1SA, constructed with BS1, was reliable for the discrimination of seven different aldehydes and identification of unknown aldehyde samples. BS1 was also used to prepare a fluorescent testpaper for visual detection of formaldehyde vapor.

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.
