DonnerstagAC Kolloquium - Prof. Dr. T. Sasamori - University of Tsukuba
Chemistry of π-bond systems between heavier group 14 elements The lecture highlights how π\piπ-bonded compounds of heavier group 14 elements feature a high-lying HOMO, a low-lying LUMO, and thus a narrow HOMO–LUMO gap—key for advanced organic optoelectronic materials and efficient electron transfer. [Takahiro Sasamori lecture.pdf]The talk also discusses the broader motivation of designing systems capable of activating inert small molecules such as CO2\mathrm{CO_2}CO2 and N2\mathrm{N_2}N2 without transition metals. Prof. Sasamori will present recent synthetic strategies and unique reactivity of highly stable π\piπ-bonded compounds bearing reactive functional groups (including H and Br substituents) as well as heavier group 14 triple-bond systems.

MontagAC Colloquium Prof. Dr. T. Baumgartner - York University Toronto
Recent research in the area of functional π-conjugated materials has shown that the incorporation of main group elements such as boron, silicon, selenium, tellurium, and phosphorus in particular, is an efficient strategy to obtain sustainable materials with intriguing properties for a host of practical applications ranging from organic light emitting devices (OLEDs), field-effect transistors (OFETs), photovoltaics (OPVs), batteries, to sensors and metal-free catalysts for chemical transformations.

MontagAC Colloquium Prof. Dr. Martin Caleb - Baylor University USA
Carborane Substituted Boron Lewis Superacids Dodecacarborane clusters (C2B10H12) have been known for 60 years yet their application as an electron withdrawing group is not well established. Our group has been preparing boranes that feature two or three ortho-carboranes as bulky electron withdrawing groups on boron to enhance the Lewis acidity. The reactivity of the new boranes is compared to the state-of-the-art boranes with fluoroaryl groups revealing significantly greater Lewis acidity. The large steric profile of the carboranes make it an excellent Lewis acid partner in frustrated Lewis pair chemistry. A compound with two carboranes and a hydride is one of the most potent hydroboration reagents known that is capable of the uncatalyzed hydroboration of cyclopropanes. The properties of the feature compounds, mechanisms of the reactions, and isolation of reactive intermediates will be discussed.

MontagModelling the pyroelectricity of ferroelectric perovskite oxides
Pyroelectric materials convert fluctuating heat flows to electrical energy. The most efficient pyroelectric materials are inorganic ferroelectrics, that is, materials showing spontaneous, switchable electric polarization. We have developed a computational methodology to study the atomic-level mechanisms of pyroelectricity in inorganic ferroelectrics. We determine the primary pyroelectric coefficients by combining hybrid density functional calculations with self-consistent phonon theory and the Berry phase approach for polarization. Secondary pyroelectric coefficients are evaluated by combining thermal properties from quasi-harmonic approximation with elastic and piezoelectric coefficients.

FreitagSYMPO 2026 - Bonner Symposium für Katalyse und Nachhaltigkeit
Das jährliche Bonner Symposium für Katalyse und Nachhaltigkeit, SYMPO, findet am 7. August 2026 an der Universität Bonn auf dem neu errichteten Campus Bonn-Poppelsdorf statt. Forscher aus dem Bereich nachhaltiger Prozesse und Katalyse (thermisch, elektrochemisch, biologisch…) kommen zusammen, um sich offen über den aktuellen Stand der Forschung und der Fortschritte auf diesem Gebiet auszutauschen. Diese Konferenz soll als Plattform dienen, um Kooperationen aufzubauen und innovative Ideen für die Zusammenarbeit zu fördern. Die SYMPO-Konferenz fördert zudem junge Wissenschaftler, insbesondere diejenigen in der Anfangsphase ihrer Karriere, und bietet ihnen die Möglichkeit, ihre eigenen Arbeiten und Ansätze vorzustellen und mit einem breiten Publikum zu diskutieren. Wir freuen uns auf ein spannendes und abwechslungsreiches Programm mit einer Mischung aus Vorträgen und Posterpräsentationen. Alle interessierten Teilnehmer sind herzlich in Bonn willkommen!

FreitagSYMPO 2026 - Bonn Symposium on Catalysis and Sustainability
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!
