Dr. Beatrice Adelizzi “Tuning non-covalent interactions: from synthetic supramolecular copolymers to proteins and DNA”
Beatrice Adelizzi Project Leader – Inkjet Synthesis at DNA Script Abstract Despite being inherently weak and dynamic, non-covalent interactions play a fundamental role in dictating the organization of molecules, materials, and (bio)polymers. Understanding such interactions allows one to tune their strength, predict the self-organization of the system, and enhance (or inhibit) targeted reactivities. Despite the wealth of research in the field of supramolecular chemistry, the challenge of mastering a system becomes exponentially more difficult as its complexity is increased. This…

Gabriel J. Lovinger Harvard University Abstract The discovery of fundamental reactivity and the development of selective catalytic methods to precisely construct functional molecules and chiral motifs is essential for the development of the natural sciences. This seminar will cover several cases in which the exploration of how catalysts interact with reactive intermediates has led to the discovery of new manifolds of reactivity and modes of selective catalysis. The first part of the seminar will discuss the development of enantioselective transition…

Prof. Eric. Jacobsen Harvard University Abstract In the minds of chemists at least, there is no doubt that many of the most pressing challenges facing humanity – such as health, the environment, and energy – will have to be addressed using chemistry. Catalysis lies at the heart of nearly every challenge in modern chemistry, cutting across all of its subdisciplines and connecting to fields as diverse as biology, materials science, and engineering. However, chemists’ ability to design new catalysts for…

Prof. Eric. Jacobsen Harvard University Abstract My research program has been dedicated to the discovery of catalytic systems that control stereochemical outcomes in organic reactions of interest. In the course of our efforts, we have had occasion to perform deep mechanistic analyses of the catalysts we have discovered. In this lecture, I will relate three different stories where seemingly minor misbehaviors in our experimental data were examined closely and found to reveal unexpected insights into the catalytic mechanisms and ultimately…

Prof. Simone Fabiano “Organic Mixed Conductors for Brain-Inspired Electronics”
Prof. Simone Fabiano Linköping University, Sweden Abstract Biointegrated neuromorphic hardware holds promise for new protocols to record and regulate signaling in biological systems. Traditional neuromorphic systems relying on silicon face limitations in bio-integration due to circuit complexity, poor biocompatibility, and low energy efficiency. Organic mixed ionic-electronic conductors (OMIECs), owing to their structural resemblance to biomolecules and coupled ionic-electronic transport functionalities, offer an excellent solution for bridging electronics and biology, facilitating energy-efficient signal transduction. In this presentation, I will explore…

Prof. Eric Vauthey University of Geneva Abstract A large number of symmetric molecular architectures, including the reaction centre of photosynthetic bacteria, undergo photoinduced charge transfer along one of several energetically equivalent pathways, resulting in a breaking of the symmetry. Some of our efforts toward a better understanding of the origin and dynamics of these processes will be presented. Two types of photoinduced symmetry-breaking charge-transfer process occurring in symmetric molecular systems will be addressed. The first concerns charge separation between two…
