Interfaces are important areas where reactions are taking place or where interactions on the molecular level determine the energetics. However, often it is difficult to obtain molecular level information from an interface, as the surrounding bulk molecules overwhelms the signal from the few interfacial molecules. In this talk we will discuss how sum frequency generation spectroscopy (SFG) can be used to obtain molecular level information of interfaces. Sum-frequency generation (SFG) spectroscopy is a technique capable of retrieving vibrational information of selectively interfacial molecules even if bulk amounts of liquid are present. Here, we will discuss two recent highlights of our work.
In the first part of the talk we will aim to understand the molecular scale interactions of a switchable emulsifier comprising poly(methacrylic acid) (PMAA) and poly(ethylene glycol) methacrylate (PEGMA). This emulsifier forms stable oil/water emulsions at pH > 10, but the emulsion becomes unstable at pH < 3 due to droplet aggregation. Using SFG, we study the PMAA/PEGMA polymer deposited on an aqueous subphase. We find that at pH 2.5, both MAA-EG H-bonds and MAA = MAA cyclic dimers contribute to droplet aggregation in the emulsion. In contrast, at pH 11.5 deprotonation and solvation of the PMAA component lead to a polymer restructuring forming a negative shell around the droplets, electrostatically stabilising the emulsion in alkaline conditions.
In the second part of the talk will follow the dynamics of water molecules at the TiO2-water interface after photoexcitation with UV light. A critical step in photocatalytic water dissociation is the hole-mediated oxidation reaction. Using femtosecond time-resolved SFG spectroscopy we could obtain molecular-level insights into the mechanism of this complex reaction under realistic conditions. Following the generation of holes at the surface immediately after photoexcitation of the catalyst with UV light, water dissociation occurs on a sub-20 ps timescale. At both pH 3 and 11, we observe the conversion of H2O into Ti-OH groups and the deprotonation of pre-existing Ti-OH groups. This study provides unique experimental insights into the early steps of the photo-induced dissociation processes at the photocatalyst-water interface.
Ellen Backus obtained her PhD in 2005 at Leiden University in the Netherlands. After a PostDoc at the University of Zurich, she moved back to the Netherlands for an independent PostDoc position at AMOLF in Amsterdam. In 2012, she joined the Molecular Spectroscopy department at the Max Planck Institute for Polymer Research as a group leader. Since 2018 she is professor for physical chemistry at the University of Vienna and leading the Ultrafast and Nonlinear Spectroscopy group. The overall research goal of her group is understanding the structure, relaxation dynamics, and reactivity of soft matter at interfaces and in bulk on the molecular scale.
