MontagAC Colloquium - Asst. Prof. Jonathan Kephart
Asst. Prof. Jonathan Kephart, Cornell University, USA 'Coordinative Tug-of-War on a Cluster Surface and the Making of Molecular Rust' Ligand-stabilized inorganic clusters bridge molecular and materials chemistry, providing atomically precise platforms to model surface reactivity and quantum-confined inorganic fragments whose properties differ from those of bulk solids. This talk will describe well-defined, surface-like reactivity in a new class of ternary clusters and preliminary efforts toward the synthesis and reactivity of unusual molecular metal oxides. ...

MittwochGDCh-Kolloquium: Prof. Dr. Hiroaki Suga
Prof. Dr. Hiroaki Suga, The University of Tokyo, Department of Chemistry: Genetic Code Reprogramming by flexizymes for Therapeutic Innovation Genetic code reprogramming is the method to redesign the genetic code restricted by 20 pro-teinogenic amino acids with other exotic building blocks. Although there are some ways to re-program the genetic code, flexizymes invented by Suga and colleagues are highly versatile cata-lysts to charge a wide range of such amino acids, including D-amino acids, beta/gamma-amino acids, and hydroxy acids. The combination of flexizyme technology with a custom-made cell-free translation system, referred to as Flexible In-vitro Translation (FIT) system, enables for ex-pression of libraries of nonstandard peptides containing exotic building blocks. This method is further integrated with mRNA display has led to the invention of RaPID (Random nonstandard Peptides Integrated Discovery) system, giving ultrafast discovery of de novo bioactive peptides.

MontagAC Colloquium - Prof. Olga Boltalina
Prof. Olga Boltalina, Colorado State University, USA 'From Serendipity to Selectivity: An Introspective Overview of Fluorine Chemistry of Molecular Carbons and Applications in Organic Electronics' Fluorinated fullerenes are a distinctive class of molecular fluorocarbons. Unlike fluorinated graphene, nanotubes or other nanocarbon materials, they have well-defined compositions and structures, which makes them uniquely suited to establishing structure–property relationships. This lecture presents an introspective account of three decades of research in this field. It discusses initial fascination of fluorine chemists with “superlubricant” C60F60, which has never been made, followed by the discovery of their exceptional electron acceptor ability and attempts to utilize as cathodes in Li primary batteries. ...

DonnerstagAC Colloquium - Asst. Prof. Lucile Chatelain
AC-Kolloquium - Asst. Prof. Lucile Chatelain, Université de Bretagne Occidentale UBO, Brest 'Bioinspired {Fe2S2} and Uranium Complexes for Small-Molecule Activation (H2, CO2 and N2)' Addressing the global energy and climate challenges requires sustainable approaches to both energy production and the valorization of abundant small molecules. Therefore, the activation of H2, CO2 and N2 is a fundamental challenge that drives the development of new molecular systems. The presentation will cover work in this field inspired by natural enzymes. [FeFe]-hydrogenases efficiently catalyze H2 into protons under mild conditions.1 Bioinspired {Fe2S2} complexes have demonstrated that proton reduction is more accessible than H2 oxidation. To activate H2, we formed inter- and intramolecular pairs between a {Fe2S2} complex coordinated by phosphine ligands and a borane-type Lewis acid.2–4 Our group demonstrated heterolytic activation of H2, validating a Frustrated Lewis Pair approach. ...

MontagAC Colloquium - Prof. Crispin Lichtenberg
Prof. Crispin Lichtenberg, Marburg University 'What’s Your Charge? Neutral, Cationic, and Anionic Bismuth Compounds for Synthesis and Catalysis' Molecular bismuth compounds can be designed to show a pronounced polarizability, low homolytic bond dissociation energies and reversible bond cleavage / formation events. We aim to exploit these properties to create uncommon structural motifs and to realize selective group transfer reactions in stoichiometric and catalytic scenarios. Granting access to well-defined neutral, cationic, and anionic compounds has been revealed as a key strategy to control and fine-tune the properties and reactivity patterns of these compounds.

DienstagGDCh-Kolloquium: Prof. Dr. Peer Kirsch
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.
