Program | Although liquid/liquid interfaces play a key role in many areas of science and technology, their properties are only partially understood. Our strategy to obtain an insight into these properties is to investigate the ultrafast excited-state dynamics of environment-sensitive molecular probes at liquid interfaces using time-resolved surface second harmonic generation, and to compare it with the dynamics of the same molecules in bulk solutions. Additionally, this approach gives rich information on how the chemical reactivity may change when going from the bulk phase to the interface. This will be illustrated with several studies of friction, ionic concentration, hydrogen bonding and chirality at liquid interfaces. | |
