Themed collection Vanadium Chemistry in the 21st Century

Guest Editors Armando J. L. Pombeiro, Manas Sutradhar and Isabel Correia introduce the New Journal of Chemistry “Vanadium Chemistry in the 21st Century” themed collection.

The most important aspects of the chemistry and structure of L-ascorbic acid (vitamin C) will be presented.

This communication presents a novel approach to set up a machine learning-ready database for epoxidation reactions, focusing on vanadium catalysts.

The synergistic combination of vanadium and pincer ligands produces complexes with potential antidiabetic, antibacterial, antiviral, antiparasitic, and anticancer activities with enhanced stability, improved bioavailability, and greater specificity.

Research on metallodrugs with biological properties remains at the forefront, focusing on the development of compounds that interact non-covalently with DNA and possess the ability to cleave the double helix strands of this biomacromolecule.

The preferential use of vanadium to form metal–protein cross-links by Mytilus edulis mussels in their byssal fibers was highlighted through a cross-disciplinary study combining histology, spectroscopy, rheology, and computational modeling.

Er³⁺/Yb³⁺ doped YVO₄ and GdVO₄ phosphors were prepared through the combustion technique and were characterized through various techniques.

This work presents a pioneering approach to the electrochemical detection of levofloxacin (LVO) in human blood samples using FVO/CN, which enhances the sensitivity and selectivity of the sensor towards the detection of LVO.

A cobalt disk surrounded by vanadium–oxygen crowns was synthesized and utilized as an oxidation catalyst for alcohols.

Alkyl pyridinium decavanadate salt interacts with cationic organic dyes in aqueous media. A crystal structure of methylene blue with decavanadate is reported for the first time.

The first BHT luminescent siderophore-type ligand has been prepared. Coordination of the selective ligand with hard metal ions, Fe^III, V^V and U^VI, quenches the emitted light permitting the quantification of metal ions at nM concentrations.

[V(N-2,6-Cl₂C₆H₃)(CHSiMe₃)(OC₆X₅)(NHC)] exhibited remarkable catalytic activities for ROMP of norbornene at 25 °C to afford ring-opened polymers not only with high cis-(93–98%) selectivity, but also with exclusive syndiotactic stereo-regularity.

Niobia-supported VPO catalysts were synthesized using the deposition–precipitation method with different VPO loadings to evaluate glycerol dehydration. The activity patterns are consistent with the acidity trends.

Halogenated non-innocent vanadium(V) Schiff base mono-substituted catecholates have a low stability and anti-proliferative properties similar to vanadate. A linear correlation between complex redox potential and the catechol pK_a was observed.

A series of mesoporous ceria-supported vanadium oxide catalysts were prepared and explored for aerobic oxidation of ethylbenzene to acetophenone without the involvement of any solvent or additive.

Replacement of phen in [VO(Narg)₂] induces greater π electronic delocalization, thus improving antioxidant action. However, due to its lipophilic character, cellular uptake of V is increased, leading to enhanced pro-oxidant and anticancer effects.
