New tetradentate Schiff base chloro complexes of U(iv) and Th(iv) are prepared by salt metathesis approaches. These compounds undergo clean salt metathesis with NaN to generate stable pseudo-trans azide compounds. The uranium dichloro complex also undergoes 2 e oxidation with excess NaNO to generate the uranyl derivative. All classes of complexes are characterized by single crystal X-ray diffraction and NMR spectroscopy.

On the Mechanism of Light-Driven O Evolution by the Mn(III) Complex [Mn(salpd)(OH)] and Quinone.

In this study, we apply TD-DFT and DFT calculations to explore the mechanistic details of O evolution in an artificial system that closely resembles Photosystem II (PSII). The reaction involves mononuclear Mn(III) complex [Mn(salpd)(OH)] and -benzoquinone under light-driven conditions. Our calculations reveal that the Schiff-base ligand salpd plays a crucial role in several key steps of the reaction, including the light-mediated oxidation of [Mn(salpd)(OH)] to [Mn(salpd)(OH)] by -benzoquinone, the subsequent oxidation of [Mn(salpd)(OH)] to the key Mn(V) intermediate [Mn(salpd)(O)], and the critical O-O bond formation step.

Over the years, numerous ligand-based organotin(IV) Schiff base compounds have shown remarkable cytotoxicity and anticancer activities, but their clinical use is restricted by systemic toxicity, prompting the search for targeted therapies. Targeted delivery can be enhanced by exploiting the inherent characteristics of cancer cells such as glutamine addiction, which is essential to support cellular biosynthesis and cell growth to sustain aberrant proliferation. Our previous study revealed glutamine-conjugated organotin(IV) compounds have strong DNA/protein affinities, favorable in silico ADME profiles, and significant antiproliferative activity.

A novel fluorescence sensing nanoplatform (CDs/AuNCs@ZIF-8) encapsulating carbon dots (CDs) and gold nanoclusters (AuNCs) within a zeolitic imidazolate framework-8 (ZIF-8) was developed for ratiometric detection of formaldehyde (FA) in the medium of hydroxylamine hydrochloride (NHOH·HCl). The nanoplatform exhibited pink fluorescence due to the aggregation-induced emission (AIE) effect of AuNCs and the internal filtration effect (IFE) between AuNCs and CDs. Upon reaction between NHOH·HCl and FA, a Schiff base formed via aldehyde-diamine condensation, releasing hydrochloric acid.
