We study lanthanide coordination complexes: their synthesis, their spectroscopy, and recently, their redox behavior. We have long been interested in the photophysical processes that take place in a photoexcited lanthanide complex. In plain English this could be summarized as ‘I wonder why this emitter is so awful’. This has resulted in the study of photoinduced electron transfer in luminescent lanthanide complexes, its impact on Eu(III) emitters, and the ways to control it (left cycle below).

The transiently formed divalent lanthanide species (Ln(II)) have been used to catalyze reduction reactions. We have developed the first broadly applicable and highly chemoselective (photo)catalytic version of lanthanide-mediated reduction reactions. Our work in this area is focused on catalyst development, mechanistic studies, and the broadening of the substrate scope (right cycle above).
