We are delighted to announce our new spotlight collection on Photoinduced redox chemistry. Spotlight Collections are ongoing themed collections highlighting the best past and present work in Dalton Transactions.

This collection demonstrates the incredible breadth of ground-breaking research being undertaken in the area of photoinduced redox chemistry all over the world.

Many classes of inorganic complexes and materials can participate in photoinduced redox chemistry, in which absorption of a photon generates an excited state that then undergoes an electron-transfer event with a redox partner. Many classes of inorganic compounds spanning a large portion of the periodic table, including transition metal and f-element coordination compounds, organometallic complexes, MOFs, nanomaterials, and extended inorganic solids, can undergo photoinduced redox chemistry. Fundamental studies of the thermodynamics and kinetics of these excited-state redox processes remain important, as they continue to reveal key insights into how ligand design, electron configuration, molecular structure, crystal structure, environment and composition affect the excited-state redox chemistry of these many categories of inorganic compounds. Moreover, photoinduced charge transport processes involving inorganic compounds are important elementary steps in several applications, including but not limited to solar fuels, organic photoredox catalysis, dye-sensitized solar cells, and photodynamic therapy.

This Spotlight Collection covers various aspects of photoinduced redox chemistry in inorganic compounds including excited-state redox processes involving new inorganic materials, the development of novel systems for studying and optimizing these processes, and studies using known compounds for applications related to photoinduced charge transport, highlighting the important roles that existing inorganic compounds can play in these areas. This collection will showcase the combined roles that synthetic and physical inorganic chemistry, including time-resolved spectroscopy and computational studies, play in driving fundamental and applied research in this continually evolving field of research.

This collection is guest edited by Dalton Transactions Advisory Board member Prof. Thomas Teets (University of Houston), Prof. Dr. Katja Heinze (Johannes Gutenberg University Mainz) and Prof. Paul Elliott (University of Huddersfield).

We are delighted to announce our new spotlight collection on Metallocycles and Metallocages. Spotlight Collections are ongoing themed collections highlighting the best past and present work in Dalton Transactions.

This collection demonstrates the amazing breadth of ground-breaking research being undertaken in the area of metallocycles and metallocages all over the world.

Metallocycles and metallocages are discrete, 2D and 3D metal-organic architectures. These beautiful and often complex structures can be formed from relatively simple building blocks through self-assembly processes centred around transition metal and lanthanide coordination chemistry. The diversity of accessible topologies and sizes, combined with their well-defined cavities, make them fascinating synthetic targets and attractive hosts in supramolecular chemistry. This Spotlight Collection aims to celebrate recent developments in the field, highlighting both fundamental and applied research.

Fundamental research into the construction and structural interconversion of new cages and metallocycles remains a valuable and popular research topic, while new and varied applications of these structures continue to develop and expand. Examples found within this collection include studies of spin and magnetism, hierarchical self-assembly into gels and applications in catalysis, separations, cancer therapeutics and optical detection.

This collection is guest edited by Dalton Transactions Advisory Board member Professor Lin Xu (East China Normal University), alongside Dr Cally Haynes (University College London) and Dr James Lewis (Imperial College London).

We are delighted to announce our new spotlight collection on Fluorinated ligands. Spotlight Collections are ongoing themed collections highlighting the best past and present work in Dalton Transactions.

This collection focuses on fluorinated ligands and their effects on physical properties and chemical reactivity.

Fluorine embodies reactivity and inertness, both of which are exploited by inorganic chemists. It is the most electronegative element in the periodic table (3.98 on the Pauling scale) and has a remarkably high reduction potential (2.87 V).  The van der Waals and covalent radii of fluorine are quite short (ranked third, only after the first-row elements hydrogen and helium), making it unusually small for its atomic number. The homonuclear bond in F₂ is particularly reactive while some heteronuclear bonds involving fluorine are remarkably stable. The combined effects of these features on fluorine-containing molecules are often unmatched by any other element, for example with carbon, where it forms very robust, chemically inert single bonds; the BDE of C-F compared to C-H bonds in CF₄ and CH₄ are 546.8 and 439.3 kJ/mol, respectively.

Metal complexes of fluorinated ligands in comparison to their non-fluorinated, hydrocarbon counterparts, usually display different properties such as relatively high thermal and oxidative stability, volatility, diminished vibrational modes and shifted spectroscopic features (absorption and emission), as well as unique reactivity profiles. They are also ideal for applications in fluorous-biphase media and supercritical CO₂. Additionally, fluorine containing anions such as [BF₄]^–, [SbF₆]^–, [B(C₆F₅)₄]⁻, and [B{3,5-(CF₃)₂C₆H₃}₄]⁻ are among the weakest donors known. This Spotlight collection brings together contributions by leading researchers on this topic to highlight some of the fascinating developments in fluorinated supporting ligands, C-F inertness, electron-withdrawing effects of fluoro-substituents, the weakly-coordinating nature of fluorinated anions, efforts to functionalize C-F bonds, and species that selectively deliver F, F^· and F^–.
