Summary: A new Schiff base multiple correspondence fluorescent probe, (E)-2-(2-hydroxybenzylidene) hydrazine-1-carboxamid (L), was synthesized for selective sensing of Cu2+ and Mg2+ ions. L showed excellent selectivity and high sensitivity toward Cu2+ in turn off mode with a detection limit of 40.5 nM in 10 mM, pH = 7.0 PBS buffer. On the other hand, L exhibited highly selective and sensitive fluorescence sensing ability for Mg2+ in turn on mode with a detection limit of 9.5 nM when acetonitrile was used as the solvent. The binding modes of L with Cu2+ and Mg2+ were investigated, and satisfactory results were obtained when L was used to detect Cu2+ and Mg2+ in real water samples.

Summary: Uniform two-dimensional platelets with tailorable shapes and controlled sizes are successfully constructed by creating new nuclei from a donor-acceptor molecule and 1-hexanol in this study. The growth of these platelets can be regulated by simply varying the amount of 1-hexanol, and complex concentric multiblock 2D heteroplatelets can be obtained by sequential and alternative addition of different donor-acceptor molecules. These platelets exhibit enhanced photostability compared to those obtained by conventional self-assembly without 1-hexanol involvement.

Summary: This paper introduces the development and proof-of-concept testing of a trace analysis technique called F-SPE, which combines a fluorescent sensor with solid phase extraction (SPE) to simplify the procedure while maintaining low limits of detection (LOD). The technique involves concentrating an analyte onto a fluorophore-modified membrane and measuring its amount by quantifying the quenching of the fluorophore. The method was demonstrated by impregnating a SPE membrane with a perylene diimide (PDI) fluorophore for the low-level detection of organic amines and amine-containing drugs.
