Talk abstract

An interesting concept, permitting the study of a variety of new photophysical phenomena is based on the assembly of modulated light- and electron-responsive materials. Three-dimensional structure of such materials is often driven by noncovalent interactions that control intermolecular interaction patterns and condensed state geometries. However, the resultant optoelectronic response may also be significantly impacted by the vibrational flexibility of molecules in an assembly. The prediction of noncovalent interactions, the control of supramolecular assembly and the consideration of materials’ dynamics are challenging, limiting further modification of molecules for new materials with desired photoinduced properties.

In my talk, I will demonstrate the application of multiscale modeling and automated workflow tools for understanding the assembly of functional organic molecules in pillar-layered and surface-anchored metal-organic frameworks. I will explain the prediction of their photoconductive, photoswitchable and chiroptical properties, as well as the molecular bases of light-induced phenomena and the influence of noncovalent interactions and molecular motions.

Talk abstract

Interacting with living cells has always been a challenging problem. The biological environment can be associated with an electrolyte in which the commonly used electrical signals tend to spread. Furthermore, contactless and wireless methods are extremely appealing due to their ability to leave unaltered the cell and tissue condition. Following this idea, light represents a clean and spatiotemporal precise tool to achieve effective bio-stimulation. Material-based light-transducers, such as conjugated molecules and macromolecules, have proven their efficacy at the interface with living cells and tissues. The interaction is possible thanks to the photophysics, biocompatibility and versatility in chemical synthesis of the molecular actuators. Exploiting a biomimicking approach a molecular phototransducer will be presented analysing both its photo/chemical properties and its ability to control cell activity. Finally as a case of study its application as a pacing tool will be presented validating this molecular phototransducer as an innovative tool for muscle cells contraction.

Agenda
Reactive intermediates are central to the understanding of chemical reactions. Due to their short lifetime their detailed study is challenging. One method that allows convenient study of highly reactive species is cryogenic matrix isolation. Here, reactive molecules or their precursors are frozen out in a large excess of inert gas (mostly argon, but also neon, krypton or xenon can be employed). This precludes intermolecular reactions and provides an environment for the spectroscopic study of the entrapped molecules. Typically, infrared spectroscopy, UV/vis spectroscopy and electroparamagnetic spectroscopy are employed for the analysis. The method is also well suited for the study of weak intermolecular interactions, e.g., hydrogen bonding, dative interactions etc. I will present the method and some of its seminal applications in the student lectures before reporting our own work in this area and its interconnection to the development of novel materials for energy storage.

About the lecturer

Professor Dr. Holger F. Bettinger was born in Nördlingen, Germany, in 1970. He studied chemistry at the Friedrich-Alexander Universität Erlangen-Nürnberg and graduated in 1998 with a Ph.D. under the supervision of Prof. Paul von Ragué Schleyer. After postdoctoral research at the University of Georgia (Athens, GA, USA), Ruhr-Universität Bochum (Germany) and Rice University (Houston, Texas, USA), he started his independent research group at Bochum in 2001 and achieved habilitation in organic chemistry in 2005. Since 2008 he is professor at the Eberhard Karls University Tübingen, where he currently acts as director of the Institute of Organic Chemistry. His research interests include reactive molecules of organic and organometallic nature as well as their use as building blocks in organic materials. He received a number of awards among them an ERC Synergy Grant, and is author of more than 190 papers.
