Photoregulated organocatalysis - From caged catalysts to photoswitchable catalytic systems (PHOTORCA)
Start date: 01 Apr 2009, End date: 31 Mar 2011 PROJECT  FINISHED 

"The project combines the two recent and versatile methodologies of organocatalysis and photoregulation with the objective to develop photoregulated organocatalytic systems. Together with the proposed immobilization in order to recycle these innovative catalysts such systems are expected to be of great value in the context of sustainable chemistry as control of reactions should allow for minimizing the formation of byproducts and therefore should create more efficient synthetic processes. If compared to highly efficient and selective enzymatic transformations, organocatalysis as their “biomimetic counterpart” misses a regulating control as frequently found in natural systems. In this regard light can be considered as an almost ideal trigger, because of its non-invasive interaction with matter, but also because of the disitinct advantage to provide very good temporal and spatial resolution. As first proof of principle we want to modify the activity and control the selectivity of organocatalysts in situ by the use of light."
