Summary: Developing materials that can differentiate between chemically similar substances is challenging, especially for aliphatic and aromatic amines. Metal-organic frameworks (MOFs) with permanent porosity have been designed for discriminative sensing of amines and on-site detection of ammonia. Two Co-based multifunctional MOFs were utilized, where aliphatic amines led to turn-off fluorescence and aromatic amines showed turn-on fluorescence intensities. Real-time sensing experiments with MOF-based mixed matrix membranes demonstrated an instant color change when ammonia was released.

Summary: This study prepared red-emitting rod-type aggregates L and found that the restriction of intramolecular motion and the ESIPT phenomenon played a key role in emitting red fluorescence at 597 nm. The aggregates L showed red-emitting fluorescence between pH 5.4 and 9.1, green-emitting fluorescence above pH 9.9, and non-fluorescent behavior in acidic pH. L in HEPES buffer showed a selective turn-off response towards Cu2+ with a detection limit of 2.7 μM.

Summary: A simple water-soluble carboxamidoquinoline derivative selectively binds to Cu2+ and Au3+ ions in different binding modes. With excellent selectivity and sensitivity, it can identify Cu2+ and Au3+ ions in water medium over a wide pH range. The association constants for both ions were determined and confirmed through mass spectra. The sensor shows low detection limits for Cu2+ and Au3+ ions and exhibits different sensing strategies for the two ions based on photophysical properties, FT-IR spectra, and theoretical (DFT) observations. Its usefulness was tested in various water samples.
