Based on a through bond energy transfer (TBET) between rhodamine and naphthalimide fluorophores, a fluorescent ratiometric chemosensor L was designed and prepared for highly selective detection of Fe(3+) in aqueous solution and in living EC109 cells. These significant changes in the fluorescence color could be used for naked-eye detection. The reversibility established the potential of the probe as chemosensor for Fe(3+) detection.

Novel Nitrogen Hybrid F Sensors Based on ESIPT Mechanism Achieving Super Low Detection Limits.

Luminescence

January 2025

Department of Psychiatry, Shanxi Bethune Hospital, Shanxi Academy of Medical Sciences, Tongji Shanxi Hospital, Third Hospital of Shanxi Medical University, Taiyuan, China.

Two novel nitrogen hybrid fluorescent sensors based on the ESIPT mechanism were successfully synthesized for the detection of fluoride ions (F), and they exhibit high sensitivity and selectivity with a fast response. The detection limits even reach the parts per billion level. With the addition of F, both sensors showed a ratiometric fluorescence change with a large Stokes shift.

A novel probe NIR8 decorated with colorimetric, fluorometric, turn-on, and NIR properties was designed and synthesized using the chromenylium-cyanine platform for sensitive and selective quantification of Hg in real samples. The interaction between the probe and Hg resulted in the opening of the closed spirolactam ring of the chromenylium-cyanine platform, leading to a notable color shift from yellow to green. Concurrently, ratiometric spectral changes at 380 and 725 nm for UV-Vis and signal enhancement at 755 nm for fluorescence were observed.

Designing and preparing highly sensitive and accurate fluorescent chemosensors for monitoring tetracycline antibiotics remains a challenge. Herein, a fluorescent chemosensor based on lanthanide metal-organic frameworks (Ln-MOFs) is proposed to realize high-precision monitoring by adjusting the ratio of lanthanide ions. Ln-MOFs with good aqueous stability were prepared by a solvothermal method using Eu, Tb and the ligand 4,4',4″-s-triazine-2,4,6-triyltribenzoic acid (HTATB) in DMF/NMP/HO.

Article Synopsis
  • A low-cost hydrothermal method was used to create nitrogen-, fluorine-, and sulfur-co-doped carbon dots (NFS-CDs) that are highly fluorescent, showing dual emission peaks and a quantum yield of 24.7%.
  • NFS-CDs demonstrated strong selectivity and sensitivity for detecting mercury (Hg) ions in solutions, exhibiting significant fluorescence changes in their presence, with a reliable detection limit and optimal stoichiometric ratio established.
  • In practical applications, NFS-CDs effectively detected Hg in natural water samples with high recovery rates and low variability, and they also showed antibacterial activity against E. coli and S. aureus while being safe for use in live cell imaging.

Investigating chemosensors that are capable of quantifying pressure in solution, particularly hydrostatic pressure, which is one of the mechanical forces, is an attractive challenge in chemistry from the viewpoint of "mechano"-science. Herein, we report the investigation of chiral porphyrin tweezers, and , comprising different flexible linkers; and displayed distinct ratiometric signaling by using the higher excited S state with a standard excited S level. A novel operative mechanism using the S/S fluorescence ratio was revealed using hydrostatic pressure-ultraviolet/visible (UV/vis), fluorescence/excitation, circular dichroism spectroscopy, and lifetime measurements, which can be further controlled by the open-closed conformational change inherent in the tweezer skeleton.
