Summary: Molecular architecture with different fluorophoric units can improve and effectively recognize biologically important analytes. This study presents a new strategy for designing ratiometric chemosensors that use photoinduced electron transfer (PET). The ratiometric sensor with tryptophan and anthracene demonstrates high sensitivity, excellent selectivity, and remarkable reversibility in the detection of H+ in methanol. The incorporation of a bispidine entity enables the molecule to exhibit a Turn-On behavior, where the fluorescence of the anthracene is effectively quenched by adjacent amine groups and highly sensitive recognition of protons occurs when H+ protonates the amine functionalities, resulting in the emergence of fluorescence from the anthracene group. This, combined with the reduction of fluorescence from the Trp group, leads to a highly sensitive ratiometric response, especially at low [H+].

Summary: Sensing temperature is crucial for understanding physiological and pathological processes. However, highly sensitive temperature sensing with organic fluorescent nanothermometers is challenging. In this study, a ratiometric fluorescent nanogel thermometer is developed to determine bactericidal temperature. The nanogel exhibits reversible spectral changes based on its hydrophilic-to-hydrophobic transition, and its emission intensity can be correlated to external temperature. The nanogel shows promise in predicting photothermal antibacterial effects and other temperature-related biological events.

Summary: This paper investigates the synthesis and application of a new phosphorescent material. A rhodamine dye containing boronic acid and spirolactam ring was grafted onto the surface of boronate nanoparticles, resulting in a phosphorescent composite. It was found that the addition of Al3+ changed the phosphorescent color, and the concentration of Al3+ could be detected based on the ratio of emission intensities. The study also observed a metal ion-dependent discernable color in the afterglow on a nanoparticle-coated filter paper.

Summary: This study reports the design, synthesis, and application of a highly solvatochromic coumarin derivative (compound 1) for water detection. The solvatochromism of compound 1 is attributed to the presence of an electron-withdrawing aldehyde substituent and an electron-donating diethylamino group. Compound 1 shows significant fluorescence responsiveness to polar protic solvents, especially with a pronounced decrease in fluorescence upon the addition of small amounts of water. This water-based responsiveness is utilized in the development of a fluorescent water sensor with rapid, sensitive, and irreversible fluorescence quenching to both liquid water and water vapor.

Summary: The work investigated the fluorescent properties of probe HL and its mechanism for sensing Al3+ ion. HL has two competing deactivation processes: ESIPT and TICT. The TICT state, obtained by rotating the C-N single bond, is nonemissive and can quench the fluorescence. However, the formation of strong coordinate bonds between HL and Al3+ prohibits the TICT state and turns on the fluorescence.

Summary: Monodispersed nanoscale NaYF4:Ln(3+) nanoparticles with surface-passivated core-shell structures exhibit intense X-ray-charged persistent luminescence and narrow-band emissions tunable from 480 to 1060 nm. The mechanism for persistent luminescence in NaYF4:Ln(3+) is proposed through thermoluminescence measurements and the host-referred binding energy (HRBE) scheme, suggesting the role of lanthanide ions as effective electron traps. These uniform and spherical nanoparticles are dispersible in solvents, enabling new applications such as 3-dimensional optical information storage and inkjet-printing multicolor persistent luminescent nanoparticles.

Summary: This article investigates the effects of electron- and hole-doping on a 2D Cr2Ge2Te6 (CGT) monolayer, revealing that electron-doping induces half-metallicity and enhances magnetism, particularly in improving ferromagnetic stability. Adsorption of alkali and alkaline-earth metals manipulates electron-doping effects by pushing up the Fermi level, allowing the spin-up channel to conduct while the spin-down channel remains insulating.
