Improved Optical Performance Analysis of YAG:Ce, NCS:Sm, and CAO:Mn Phosphors Physically Integrated with Metal-Organic Frameworks.

This research presents a thorough examination of the optical properties and performance enhancement strategies of synthesized phosphors, namely, yttrium aluminum garnet doped with cerium (YAG:Ce), sodium calcium silicate with samarium (NCS:Sm), and calcium aluminate oxide doped with manganese (CAO:Mn). The study delves into the synthesis processes of the phosphors, illumination of the crystal structures, and enhancement of luminescent characteristics. Additionally, the paper extends to the synthesis and analysis of {[Cu(μ-dmg)(im)]·3HO} (PKY159), and the coordination polymer (CP) was added the phosphors to explore a novel approach for enhanced optical performance.

Sensitivity to NH Vapor: Synthesis and Characterization of Five New Coordination Polymers Based on 2,2-Dimethylglutaric Acid and Bis(triazole)-Derived Ligands.

Five new coordination polymers (CPs) were obtained as a result of hydrothermal reactions of 2,2-dimethylglutaric acid (Hdmg) and 1,4-bis(1-1,2,4-triazol-1-ylmethyl)benzene ()/1,2-bis(1-1,2,4-triazol-1-ylmethyl)benzene () ligands with some metal ions [Co(μ-dmg)(μ-obtx)] (), [Zn(μ-dmg)(μ-obtx)] (), [Cd(μ-dmg)(μ-obtx)] (), [Co(μ-dmg)(μ-pbtx)] (), and [Cd(μ-dmg)(HO)(μ-pbtx)] (). All of the compounds were characterized by elemental analysis, FT-IR spectroscopy, single-crystal X-ray diffraction, powder X-ray diffraction, and thermal analysis techniques. The single-crystal X-ray studies show that all compounds exhibit 2D layer structures.

Tuning CO sensing properties of HPTS along with newly synthesized coordination polymers (CPs).

Coordination polymers (CPs), new functional hybrid materials, have received important attention due to their structural features and many different applications such as gas storage, catalysis, energy storage, small molecule adsorption, luminescence, and chemical sensors. In this study, two newly synthesized metal-organic frameworks (MOFs); [Mn(µ-dmg)-(µ-dmg)(µ-bipy)] (CP1) and [Mn(µ-dmg)(µ-dmg)(µ-dpeten)] (CP2); were used for sensing of gaseous carbon dioxide with a spectrofluorometric method with a dye, 8-hydroxypyrene-1, 3, 6-trisulfonic acid (HPTS) as matrix additive material for the first time. The ion-pair form of the HPTS was used in the polymethyl methacrylate matrix as a thin film form.

Screening organometallic thiophene containing thiosemicarbazone ruthenium (II/III) complexes as potential anti-tumour agents.

The new ruthenium (III) complex has been synthesized and characterized by elemental analysis, FT-IR, UV-Vis, EI-Mass, EPR spectroscopy, and magnetic susceptibility measurement. Cytotoxic effects of organoruthenium (II/III) complexes 1a, 1b, and 2a, and their ligands (TSC and TSC) in cultured human ovarian (A2780, SKOV-3, and OVCAR-3) and colon (DLD, CCD18Co, and Caco-2) cells have been investigated comparing reactivity of the Ru (II/III) complexes and their free TSC ligands. The complexes exhibit higher cytotoxicity in three cancer cell lines than in normal cells.

Ruthenium (II) complexes of thiosemicarbazone: synthesis, biosensor applications and evaluation as antimicrobial agents.

A conformationally rigid half-sandwich organoruthenium (II) complex [(η(6)-p-cymene)RuClTSC(N-S)]Cl, (1) and carbonyl complex [Ru(CO)Cl(PPh3)2TSC(N-S)] (2) have been synthesized from the reaction of [{(η(6)-p-cymene)RuCl}2(μ-Cl)2] and [Ru(H)(Cl)(CO)(PPh3)3] with thiophene-2-carboxaldehyde thiosemicarbazon (TSC) respectively and both novel ruthenium (II) complexes have been characterized by elemental analysis, FT-IR and NMR spectroscopy. The peripheral TSC in the complexes acts as an electrochemical coupling unit providing the ability to carry out electrochemical deposition (ED) and to form an electro-deposited film on a graphite electrode surface. The biosensing applicability of complexes 1 and 2 was investigated by using glucose oxidase (GOx) as a model enzyme.
