Switchable catalysis

We are interested in catalysis toggled (switched on and off) in response to external stimuli,  especially when it happens due to geometric constraints.

 

In 2016, we reported on a photo- and thermally activated catalyst for olefin metathesis:

Very recently, we introduced a new concept of controlling chemical reactions by light through the reversible hiding of catalytic centers within a crowded chemical environment:
