Aluminum contains three valence electrons and is the most electropositive element in the p-block. Examples of synthesizing transition-metal complexes with a three-coordinated aluminum ligand remain limited. They can be classified to the following methods: A nucleophilic attack of anionic transition-metal complexes to an aluminum electrophile, the coordination of a base-stabilized Al species to a metal, elimination of alkane via a metathesis reaction, an oxidative addition of an Al–H bond to a metal center in a low oxidation state, insertion of Al species into a metal-halogen bond, and transmetallation of the Al anions to metal halides. In the presentation, our latest contribution to the chemistry of early transition metal-aluminum and main group metal-aluminum complexes using the method will be discussed.

The annual Bonn Symposium on Catalysis and Sustainability, SYMPO, will take place on August 7th, 2026 at the University of Bonn in newly constructed Bonn-Poppelsdorf campus. Researchers from the field of sustainable processes and catalysis (thermal, electro, bio…) will gather for an open exchange on the state-of-the-art and progression of the field. This conference is meant to be a platform to build collaborations and foster out-of-the-box collaborative ideas. The SYMPO conference further promotes young scientists, especially those in the early stages of their careers, and offers the opportunity to present their own work and approaches and discuss them with a broad audience. We are looking forward to an exciting and varied programme featuring a combination of oral and poster presentations. All interested participants are warmly welcomed to Bonn!

Prof. Dr. Peer Kirsch, TU Darmstadt: Self-Assembled Monolayers for Molecular Electronics and Spintronics Functionalized self-assembled monolayers (SAMs) can be used as active components in electronic and spintronic devices. SAMs composed of dipolar, conformationally flexible phosphonic acids enable elec-trically switchable tunnel junctions with memristive characteristics. The performance of such organic devices is comparable to that of their state-of-the-art inorganic counterparts. The big advantage of organic systems is their intrinsic functional versatility: a rather complex property profile can be easily designed into the individual component molecules, whereas deposition and device fabricating pro-cesses remain always the same. A potential challenge of many SAM systems - thermal stability - was resolved by using thermally and chemically robust phosphonic acids as anchoring groups which are compatible with oxide and nitride substrate materials common in electronics industry.
