We are interested in photochemical transformations and how to use light to trigger chemical reactions 


We are developing new molecular photoswitches and motors able to move at the nanoscale upon external light stimulus


We use the physical organic chemistry toolbox to study reaction mechanisms at the ground and excited state

About us

A synergy of organic synthesis spectroscopy and computational chemistry

We are the organic photochemistry group of Dr. Stefano Crespi, affiliated with the Synthetic Molecular Chemistry Program of the Ångström Laboratory at the University of Uppsala.
