Hydrazine (N 2 H 4 ) and fluoride ion (F − ) are regarded as environmental pollutants and potential carcinogens. A dual-functional fluorescent probe (probe 1 ) was developed for both F − and N 2 H 4 with high selectivity and sensitivity. 1 was based on nucleophilic aromatic substitution reaction for N 2 H 4 detection and selective cleavage of 4-nitrobenzenesulphonyl group for the determination of F − . The limits of detection of probe for F − and N 2 H 4 were 77.82 nM and 29.34 nM, respectively, which are far below the threshold limit value (TLV) of United States Environmental Protection Agency (EPA). The home-made test strips of 1 provided the positive tool for F − and gaseous N 2 H 4 in different system. And the confocal fluorescence images indicated that 1 can quantitatively detect N 2 H 4 in living PC12 cells. Promisingly, 1 has great prospects for N 2 H 4 imaging and determining in living system.

Counterfeiting and information leakage have become critical global challenges, exacerbated by rapid technological advancements. This study presents a novel stimuli-responsive polymer, poly(imino sulfone) (PIS), synthesized via a simple C-N coupling reaction. The findings reveal that PIS exhibits fast, high-contrast, reversible color and fluorescence dual-mode stimuli-response, driven by the protonation-deprotonation of imine groups under varying acid-base conditions. Additionally, the rigid polymer structure, coupled with strong hydrogen bonding, imparts PIS excellent thermally stable (T 5% = 463 °C, T g = 245 °C), surpassing other polymers with stimulus-responsive discoloration capabilities. Notably, even at low concentrations (0.1 wt%), PIS demonstrates strong emission performance and stimulus-induced color-change behavior. The information encoded using PIS can be efficiently and repeatedly encrypted and decrypted under acid-base stimuli, thereby enhancing the confidentiality and security of the information. When integrated into polymer matrices, PIS not only imparts quick, stable and reversible dual-mode stimulus-responsive behavior but also enhances the thermal and mechanical properties of the host materials. The resultant PIS-based patterns exhibit excellent anti-counterfeiting performance. These unique properties position PIS as a promising candidate for advanced anti-counterfeiting and encryption applications.

Developing efficient tools to rapidly diagnose early plant stress becomes increasingly important due to the global food demand and the sustainable intensification of agriculture. Enzymes are highly associated with various environmental stresses in plants, some of which are considered biomarkers. Here, we report a new glutathione S -transferase (GST)-activated fluorogenic sensor (named as FPG ) for in vivo diagnostics of plant stress responses. The developed biosensor exhibits a good capability for in situ real-time fluorescence imaging of GST in living cells. More importantly, it enabled the direct visible, monitoring of plants subjected to various biotic and abiotic stresses in a non-invasive and non-destructive manner. Furthermore, FPG allowed the sensitive indication of fungal ( Sclerotinia sclerotiorum ) and viral (tobacco mosaic virus) diseases in Nicotiana benthamiana . Collectively, it reveals that the developed biosensor holds promise for the future development of high-throughput screening for plant phenotyping and the diagnosis of numerous environmental stresses.

Solid polymer electrolytes (SPEs) with high ionic conductivity, high lithium-ion transference number (t Li + ), and good mechanical properties are highly desired for solid-state lithium metal batteries. However, developing SPEs with both high ionic conductivity and high t Li + remains a challenge. Herein, a novel network structure single-ion polymer electrolyte (SIPU) with high ionic conductivity (0.12 mS cm −1 ), t Li + (0.71) and mechanical strength (1.5 MPa) was prepared by UV-initiated free radical polymerization and chemically crosslinking of the functional groups. The characterization and Density functional theory (DFT) calculation demonstrate that the construction of a cross-linked network structure not only endows the electrolytes membranes with improved mechanical strength to inhibit dendrite growth but also facilitates fast dissociation of Li + for boosting ionic kinetics. More importantly, a robust LiF-rich Solid Electrolyte Interface (SEI) was formed on the Lithium metal anode, enhancing the cycling performance of batteries. As a result, the Li symmetric cells using the SIPU electrolytes can stably cycle over 2000 h. The Li/SIPU/LiFePO 4 cells deliver excellent cycle performance and maintain stably cycling over 1000 cycles at 0.5C. The Li/SIPU/LiNi 0.8 Co 0.1 Mn 0.1 O 2 cells also have excellent cycling and rate performance. Furthermore, the Li/SIPU/LiFePO 4 pouch cells exhibit excellent performance. This work provides valuable insights into the rational design of polymer electrolytes with mechanical and electrochemical stability.
