Summary: An azine-based chromo-fluorogenic sensor, DBMN, has been introduced for cascade detection of Al3+ and PO43- ions with high selectivity and sensitivity. When Al3+ ions are added to the DBMN solution, a noticeable colorimetric change from yellow to colorless is observed due to inhibiting the intramolecular charge transfer process. The chelation-enhanced fluorescence (CHEF) from the Al3+ ions chelated DBMN complex leads to a 120 times photoluminescence intensity enhancement displaying bluishgreen fluorescence.

Summary: In this study, the binding properties of Calix[4]arene 1, which has two lower-rim isoxazolylchloroanthracene groups, towards metal ions were investigated. It was found that compound 1 displayed high selectivity for Cu2+ ions and could detect their presence through changes in color and fluorescence. The reaction between Cu2+ and compound 1 involved the reduction of Cu2+ and the oxidation of the phenol group in compound 1. Experimental results and various spectroscopic techniques provided evidence for this redox reaction.

Summary: Two new styrylpyrylium cations with ortho-nitrophenol moieties have been synthesized, showing sensitivity to trace water and leading to the formation of a new band at 600-800 nm with fast quenching of fluorescence emission. Compound 1a has the best sensitivity with detection limits of 0.003% vol. in acetone and 0.004% vol. in acetonitrile. The absorption changes taking place after the addition of water occur in the range 600-800 nm, which is uncommon in this research field.

Summary: This paper demonstrates the fabrication of silica-shell-coated magnetic nanoparticle clusters (SMNCs) and subsequent surface engineering to produce zwitterionic and primary amine ligands on SMNCs. The hydrodynamic size and zeta potential of SMNC-ZW/Am can be flexibly tuned by controlling the relative amounts of zwitterionic and primary amine ligands. SMNC-ZW/Am shows higher colloidal stability and reduced nonspecific adsorption compared to bare SMNC, making it a potential antifouling nanosubstrate for separation and bioanalysis.

Summary: Cation exchange (CE) is a method that can convert the chemical composition of nanocrystals while preserving their size, shape, and crystal phase. In this study, CE reactions in a porous nanostructure of supra-quantum dots (SQDs) were investigated and found to exhibit ultrafast and complete reactions, with a rate comparable to that of smaller quantum dots (QDs). The conservation of size and shape in SQDs after CE reactions suggests the presence of internal voids that compensate for lattice constant changes. The results also indicate that the interaction between external cations and the internal surface of SQDs accelerates the CE reaction.

Summary: The surface atom stoichiometry of Ag2S NCs is controlled through ion-pair ligand-assisted surface reactions. Different combinations of cation and anion pairs are studied, leading to the synthesis of cation-rich-surfaced, anion-rich-surfaced, and perfectly stoichiometric Ag2S NCs. The ion-pair-assisted surface chemistry enables the enhancement of fluorescence intensity and epitaxial growth performance of Ag2S NCs.
