Special Issue Information

Dear Colleagues,

Multimetallic complexes have been intriguing coordination chemists for a long time. The potential for properties exceeding the possibilities of complexes with only a single metal centre has sparked interest in various areas of both fundamental and applied research.

Over the decades, the interaction of multiple metal atoms has challenged our understanding of chemical bonding and aided in its development and refinement. Beyond intermetallic bonding, the study of magnetic properties of multimetallic complexes provides important advances in the field of molecular magnetism, which is a key research area in the development of high-density data storage devices. The lessons we have learned from enzymatic processes that work through the cooperation of two or more metal centres to accomplish challenging chemical reactions under mild conditions provide fertile ground for the fast growing field of biomimetik chemistry. Furthermore, the underlying principles are also the foundation for the development of industrial processes based on cooperative catalysis as energy- and resource-efficient alternatives to contemporary production methods. These are merely a few selected areas in which multimetallic coordination compounds have exhibited properties and reactivities unprecedented in the chemistry of monometallic complexes.

With this Special Issue, we aim to highlight the progress in the research into the chemistry of di-, tri-, and multimetallic complexes and coordination compounds and, thus, provide an account of current trends and activities in this rapidly expanding field.

Due to its ideal physical properties, fluorine-18 turns out to be a key radionuclide for positron emission tomography (PET) imaging, for both preclinical and clinical applications. However, usual biomolecules radiofluorination procedures require the formation of covalent bonds with fluorinated prosthetic groups. This drawback makes radiofluorination impractical for routine radiolabeling, gallium-68 appearing to be much more convenient for the labeling of chelator-bearing PET probes. In response to this limitation, a recent expansion of the 18F chemical toolbox gave aluminum [18F]fluoride chemistry a real prominence since the late 2000s. This approach is based on the formation of an [18F][AlF]2+ cation, complexed with a 9-membered cyclic chelator such as NOTA, NODA or their analogs. Allowing a one-step radiofluorination in an aqueous medium, this technique combines fluorine-18 and non-covalent radiolabeling with the advantage of being very easy to implement. Since its first reports, [18F]AlF radiolabeling approach has been applied to a wide variety of potential PET imaging vectors, whether of peptidic, proteic, or small molecule structure. Most of these [18F]AlF-labeled tracers showed promising preclinical results and have reached the clinical evaluation stage for some of them. The aim of this report is to provide a comprehensive overview of [18F]AlF labeling applications through a description of the various [18F]AlF-labeled conjugates, from their radiosynthesis to their evaluation as PET imaging agents.
