The reaction of the Tc(I) complex [Tc(NO)Cl(HOMe)(PPh)] with stoichiometric amounts of 2-mercatopyridine and a proton scavenger yields [Tc(NO)Cl(Spy)(PPh)] or [Tc(NO)(Spy)(PPh)], depending upon quantities of ligands employed. These two complexes have been structurally characterized. The small bite angles of the bidentate mercaptopyridine ligands cause significant deviation from octahedral coordination geometry.

This study presents the synthesis and characterization of CsNaBiCl nanocrystals (NCs) doped with varying concentrations of In to improve their luminescent properties. Utilizing a colloidal solution method, we systematically varied the In concentration to identify the optimal alloying level for enhancing the photoluminescence (PL) properties of the CsNaBiCl NCs. Structural analysis confirmed that the In-alloyed NCs maintained high crystallinity and a uniform cubic shape.

Metal-organic frameworks (MOFs) provide diverse applications across a wide range of scientific disciplines, including drug/nucleic acid (NA) delivery. In the subclass of MOFs, zeolitic imidazolate framework-8 (ZIF-8) is well regarded due to its exceptional physicochemical properties. Biomolecules can be encapsulated and released under precise conditions within ZIF, making it an important material for materials science and biomedical applications.

Highly fluorinated naphthyl aldehyde and binaphthyl aldehyde ()- were designed and synthesized for fluorous-phase-based sensing. Greatly enhanced sensitivity and chemoselectivity in going from to ()- in the fluorescent detection of cysteine has been discovered. This is attributed to the increased structural rigidity of the axially chiral binaphthyl unit in ()- upon reaction with cysteine to form the corresponding thiazolidine product.

This study highlights the importance of developing sensitive and selective sensors for use in pharmaceutical applications for the first time. A novel iron(III)-complex, constructed from unsymmetrical tetradentate NNN'O type Schiff base ligand (E)-3-((6-aminopyridin-2-yl)imino)-1-phenyl butane-1-one (LH) and its structure of it characterized by using various spectroscopic techniques such as FT-IR, UV-Vis, elemental analysis, conductivity, magnetic susceptibility measurements and the TGA method. The correlation of all results revealed that the coordination of the (LH) with the metal ion in a molar ratio of 1:1 leads to the formation of an octahedral geometry around the metal ions.
