Summary: Single-benzene fluorophores, the smallest and brightest fluorochromes known, have not been extensively studied for the design of high-performance fluorescent sensors of catalytic or enzymatic activities. In this study, new fluorescent probes based on the Tsuji-Trost reaction were developed for selective detection of palladium and other transition metals in an aqueous/organic mixed solvent with high sensitivity. The flexibility in synthesis allows for easy tuning of the emitted fluorescence color, and the yellow emission variant shows promising applicability in sensitive detection of palladium in cell-free and living cell conditions.

Summary: A Schiff base receptor with an active -NH group was synthesized for the colorimetric detection of inorganic fluoride (F-) ions in an aqueous medium. The receptor showed enhanced sensitivity for F- ions due to the presence of electron-withdrawing -NO2 groups, resulting in a remarkable color change. Characterization techniques confirmed the structural integrity of the synthesized receptors and a binding mechanism involving deprotonation of the -NH group and formation of -HF2 was proposed.

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: A dimeric quinoline-based Schiff base (DQS) was developed as a probe for the specific detection of Pb(2+) ions using fluorimetry. The binding of DQS with Pb2+ resulted in enhanced fluorescence intensity with a blue shift, attributed to the restriction of C-N rotation, C= N isomerization, and photoinduced electron transfer (PET) mechanisms. Moreover, intramolecular charge transfer (ICT) from an electron-donating morpholine group to a phenylene diamine acceptor linked to the quinoline bridge was responsible for the blue-shifted fluorescence enhancement in the DQS-Pb2+ complex.
