Permanent position for Annemarie Huijser

 We are very happy to announce that the temporary position of Annemarie Huijser is converted into a tenured one. As her research has significant overlap with activities in the PhotoCatalytic Synthesis (PCS) group, she will also move to PCS, while of course maintaining the connections with the OS group!

Cover article ChemPhysChem Qing Pan / Annemarie Huijser

The article "The Critical Role Played by the Catalytic Moiety in the Early-Time Photodynamics of Hydrogen-Generating Bimetallic Photocatalysts" by Qing Pan et al is featuring the cover of ChemPhysChem 17/2016. In comparison to the Ru/Pd photocatalyst, the Ru/Pt analogue shows complex excited state dynamics with three distinct kinetic components ranging from sub-ps to 100 ps, requiring a more sophisticated photophysical model than for the Ru/Pd complex. A new T3 excited state is observed to quench triplet metal-to-ligand charge transfer (3MLCT) states. These insights shed light on the significant impact of the catalytic moiety on the fundamental early-time photophysics of Ru-based photocatalysts.

Novel design strategy for hydrogen generating molecular photocatalysts

Novel design strategy for hydrogen generating molecular photocatalysts
An international collaboration coordinated by Qing Pan and Annemarie Huijser has resulted in a new design approach for hydrogen generating photocatalysts. The authors observed that violating the commonly accepted state-of-the-art design strategy strongly improves the hydrogen generation efficiency. The novel approach shows high promise for efficient direct conversion of sunlight into green fuel. The results are published in the leading journal Chemical Communications.

JACS article Annemarie Huijser

Annemarie Huijser’s article Superior Photoprotective Motifs and Mechanisms in Eumelanins Uncovered is published in Journal of the American Chemical Society. The work describes how eumelanin, one of the two pigments in the human skin, protects us against UV radiation by ultrafast proton transfer reactions. So far, there has been a lack of knowledge on which chemical reactions UV light causes in the pigment leading to protection against or development of skin cancer.


Brief CV

From November 2011 Assistant professor, Optical Sciences, University of Twente
  • I am establishing a sub-group embedded within the Optical Sciences Group focused on tuning and optimization of energy and charge transfer dynamics in (donor-)dye-acceptor molecular complexes with photovoltaic or photocatalytic application

May 2008-September 2011

Postdoctoral researcher, Chemical Physics, Lund University, Sweden
  • I was responsible for the research program on the photochemistry of melanin model systems with increasing complexity with the objective to understand the macromolecular pigment complexes present in the human skin
  • I also built a setup for time-resolved fluorescence using streak camera detection (1-2 ps time resolution), supervised MSc and PhD students and established (inter)national collaborations to have access to advanced melanin model systems and expertise in relevant excited state quantum-chemical calculations

April 2004-March 2008

PhD student, Opto-Electronic Materials Section, Delft University of Technology, The Netherlands
  • I performed an experimental study on the impact of specific molecular organization on energy transfer dynamics in porphyrin layers with the aim to enhance the energy transfer distance: improvement realized from a few to 22 nm
