Anthraquinones are the most prominent examples for starting materials for the production of coloring compounds, antioxidants, and polymerization inhibitors, widely used as intermediates for dyes, pigments, photographic chemicals, paints, and manufacturing drugs. Probably the most important application of anthraquinone derivatives might be their use in hydrogen peroxide production, which is currently produced almost exclusively with the anthraquinone oxidation process, where hydrogen and atmospheric oxygen are employed in the reaction cycle.Due to the variety of applications, the chemistry of anthraquinone derivatives is well-known and the basic arenes scaffolds can therefore be easily modified in a few synthetic steps. However, the formation of organometallic and coordination compounds containing anthraquinone platforms has not found applications in optical sensors.Herein, we show the transformation of anthraquinone derivatives into tunable ligands for transition, and the formation of a new family of first row transition metal complexes, bearing anthraquinonic cores, in moderate to good yields. These complexes have been fully characterized in solid state (X-ray, IR and Raman), solution (multinuclear NMR and IR) and gas phase (DFT calculations) and eventually applied in gas fixation and optical sensoring.
