Summary: In this study, a new and facile D2O sensor based on singlet oxygen (1O2)-relevant afterglow luminescence of chlorin e4 nanoparticles (Ce4-NPs) was reported for distinguishable detection between D2O and H2O. The 1O2 displays a much longer lifetime in D2O compared to H2O and generates more dioxetane intermediates, leading to enhanced afterglow brightness of Ce4-NPs in D2O. Ce4-NPs can also quantitatively detect the amount of H2O in D2O with a detection limit of 1.45%.

Summary: A series of triphenylimidazole derivatives were synthesized to distinguish between H2O and D2O using wavelength-changeable fluorescence. Different fluorescence variations were observed based on the different ratios of H2O and D2O in THF/water solution. The method relies on the different Lewis acidities between H2O and D2O and can be applied to design fluorescent probes for D2O.

Summary: An anomalous solvent-induced luminescence quenching of NH2-MIL-53(Fe) in D2O is reported. This quenching is not caused by protonation or high-frequency vibrations of solvent molecules, but due to the inhibition of charge transfer by hydrogen bonding between NH2-MIL-53(Fe) and D2O. This discovery enables accurate quantitative detection of specific volume fractions of D2O in H2O.

Summary: We developed a mid-infrared laser absorption sensor for simultaneous detection of CH3CN, H2O, and CH4 in the ambient air. The sensor achieved high sensitivity and selectivity, with a detection limit for CH3CN as low as 160 ppt. The sensor's small size and lightweight make it practical for continuous monitoring of ultra-low concentrations of CH3CN.

Summary: Distinguishing D2O and H2O and determining trace H2O content in D2O solvent is a challenging problem in analytical chemistry due to their similar properties. This study found that by modifying the imine structures, both hydrolysis reactions and aggregation-induced emission (AIE) can be used as dual fluorescence signals to distinguish D2O and H2O. The hydrophobicity of imines plays a crucial role in modulating the fluorescence signals in D2O and H2O solvents. Among the tested imines, probe 3 condensed from 2-naphthylamine and salicylaldehyde shows great potential for accurately measuring H2O content in D2O solvent, especially in low H2O content range, using ratiometric emission signals.

Summary: The solvent environment significantly affects the luminescence performance of Ln-MOFs. This study investigates the photoluminescence behavior of Ce/Eu@Gd-MOFs in H2O and D2O, revealing a 711.19% improvement in emission intensity in D2O compared to H2O. The enhanced luminescence is attributed to the difference in vibrational frequencies of functional groups in H2O and D2O, as well as the vibrational coupling between deuterated hydroxyl groups, H3BTC ligands, and Ce3+ ions. These mechanisms contribute to the energy transfer through vibration-vibration interaction and have potential applications in detecting D2O in H2O.

Summary: Distinguishing between water (H2O) and deuteroxide (D2O) is a challenging task due to their similarities in size, shape, and chemical reactivity. This study investigates the enhanced optical properties of a water-soluble porphyrin in D2O and proposes a convenient method for distinguishing between H2O and D2O using electrochemiluminescence (ECL) analysis, which shows a lower detection limit.

Summary: A novel and fluorescent zinc-organic framework sensor with excellent Cu2+ detection and enrichment capabilities has been synthesized and characterized. It demonstrates selective quenching of fluorescence by Cu2+ in a linear concentration range, with a low limit of detection value. The interaction between the active coordination site of the sensor and Cu2+ determines the quenching mechanism, allowing for effective detection and enrichment of trace amounts of Cu2+ in aqueous media.

Summary: Aggregation-induced electrochemiluminescence (AIE-ECL) is a method to solve the water insolubility and aggregation-caused quenching problem of organic luminescence probes. This study revealed the AIE-ECL properties of rigid indenes and achieved ultrasensitive detection of D2O in H2O using the indene-based AIE-ECL system. Our research provides a strategy to improve the luminescence performance of AIE-active luminophores and establishes a superior sensor for D2O.

We report here the scalable synthesis of chemically homogeneous, functionalized nanothreads through the solid-state polymerization of 2,5-furandicarboxylic acid. The resulting product possesses high-density, pendant carboxyl functionalization along both sides of the backbone, enabling new opportunities for the post-synthetic processing and chemical modification of nanothread materials applicable to a broad range of potential applications.

Summary: This study presents a series of Ce3+ complexes with counter cations ranging from Li to Cs. Cyclic voltammetry data show a significant dependence of the oxidation potential on the alkali metal identity. Analysis of the single-crystal X-ray diffraction data indicates a linear correlation between the degree of structural distortion and the measured oxidation potential. Solution electronic absorption spectroscopy confirms the reflection of structural distortion in the solution structure. Computational studies further validate this analysis.

Summary: A combined experimental and theoretical study of H-2 adsorption in two isostructural MOFs revealed a close agreement between theoretical and experimental results, with the primary binding site for H-2 localized near the center of aromatic rings. Inelastic neutron scattering spectroscopy identified the primary binding site for H-2 adsorption and quantum rotation calculations corroborated the energy levels observed in the spectra for both MOFs. Despite different metal ions, both MOFs exhibited similar electrostatic environments and rotational potentials for H-2 adsorption at the most favorable adsorption site.
