Mn4+ non-equivalent doped fluoride phosphor towards a short fluorescence decay time for backlighting

The non-equivalent doping of Mn4+ in the red-emitting fluoride phosphors effectively shortens the fluorescence lifetime. Herein, we successfully synthesized Rb2NaInF6:Mn4+ phosphors by an ion-exchange method. The compensation mechanism of Mn4+...

Construction of Hierarchical ZnIn2S4/C3N4 Heterojunction for Enhanced Photocatalytic Degradation of Tetracycline

Both efficient charge separation and sufficiently exposed active sites are critical limiting for solar-driven organic contaminants degradation. Herein, we describe a hierarchical heterojunction photocatalyst fabricated by in situ growth of...

C(sp3)–H bond activation by carboxylate-adduct of osmium tetroxide (OsO4)

The reaction of osmium tetroxide (OsO4) and carboxylate anions (acetate: X = AcO– and benzoate: X = BzO–) gave 1 : 1 adducts, [OsO4(X)]– (1X), the structures of which were...

Polar hydrogen species mediated nitroarenes selective reduction to anilines over an [FeMo]Sx catalyst

We herein present an efficient approach for the chemoselective synthesis of arylamines from nitroarenes and hydrazine over an iron-molybdenum sulfide catalyst ([FeMo]Sx).

Synthesis, characterization and evaluation of aqueous Zn-based quantum dots for Bioapplications

Semiconducting nanoparticles called quantum dots (Qds) present unique optoelectronic properties based on their extremely small size, composition, and spherical shape, which make them suitable for use as diagnostic and theranostic...

Reactivity of molybdenum-nitride complex bearing pyridine-based PNP-type pincer ligand toward carbon-centred electrophiles

A molybdenum-nitride complex bearing a pyridine-based PNP-type pincer ligand derived from dinitrogen is reacted with various kinds of carbon-centered electrophiles to functionalize the nitride ligand in the molybdenum complex. Methylation...

A fluorinated 2D magnetic coordination polymer

Herein we show the versatility of coordination chemistry to design and expand a family of 2D materials by incorporating F groups at the surface of the layers. Through the use...

Ligand isomerism fine-tunes structure and stability in zinc complexes of fused pyrazolopyridines

Fused-ring pyrazoles offer a versatile platform for derivitization to give finely tuned and functional ligands in coordination assemblies. Here, we explore the pyrazolo[4,3-b]pyridine (HL1) and pyrazolo[3,4-c]pyridine (HL2) backbones and their...

In defence of oxidation states

In this Perspective, some of the criticisms which have been made concerning the use of oxidation states are addressed, particularly in the context of the teaching of inorganic chemistry.

John Dalton – the man and the myth

John Dalton is one of the pioneers who transformed chemistry into the science that we enjoy today. His name is irrevocably linked with the atomic theory that underlies our modern...
