Biomolecules and nanostructures
The Optical Sciences group studies the interaction of light and matter at the nanoscale.
We do this by exploring ways to shape light and its environment. It's what we call
active and passive control. Our current focus is on the interaction of light with
biomolecules and nanostructures. We are part of Twente
University's Department of Science and Technology and member of the

The contrasting early-time photodynamics of two related Ru/Pt catalysts with very different photocatalytic H2 generation capabilities are reported. Ultrafast equilibration (535 +/- 17 fs) creates an electron reservoir on the peripheral ligands of the ester substituted complex, resulting in a dramatic increase in photocatalytic performance. The insights gained open the way towards a novel design strategy for H2 generating molecular photocatalysts.
