Homogeneous oxidation catalysis
One of the core research activities of the group is selective oxidative transformations of organic substrates with H2O2 using 1st row transition metal catalysts. Recent successes include both the discovery of a highly efficient and selective manganese catalyst system for the cis-dihydroxylation of alkenes using H2O2 and the development of this system to achieve enantioselective cis-dihydroxylation with high turnover numbers.
Electro and Photo-Responsive Self assembled monolayer modified surface
The second of the core research trusts in the group is the development of electrochemically and photochemically switchable surfaces based on self assembled monolayers and on redox polymers. In our group we focus on two key aspects of the development of responsive molecularly modified surfaces - i) developing robust approaches to both form and characterise self assembled monolayers and a wide range of metallic and non-metallic surfaces and ii) characterising the systems developed under operation conditions. In this area a wide range of surface techniques are applied to understand the behaviour of molecules on surfaces including electrochemistry, FTIR and UV.Vis-NIR spectroscopy and AFM/STM in collaboration with Dr Nathalie Katsonis.
Understanding the mechanisms of complex reactions, which follow redox reactions is a major area of interest in the group both for homogenous oxidation catalysis and responsive molecular systems. Understanding these dynamic systems require a broad base of analytical and spectroscopic techniques to be applied. In several studies ranging from understanding the behaviour of oxidation catalysts, electro- and photo-chromic molecular switches to electropolymerisation to form functional modified surfaces. Spectroelectrochemical techniques are of especial interest as it allows for structural information of the products of reactions, including redox reactions, to be identified unambiguously.
As part of the NWO-Vidi award funded research within the group the development of molecularly modified surfaces for application as functional components in micro-fluidic devices is a key research area of the group working together with the Pharmaceutical Analysis Group of Prof. dr. Sabeth Verpoorte.
