DESCRIPTION:Prof. Klaus Braagaard Møller\nTechnical University of Denmark
 \nUnderstanding\, and subsequently being able to manipulate\, the excited-
 state dynamics and decay pathways of photo-excited functional transition-m
 etal complexes is of utmost importance in order to solve grand challenges 
 in solar energy conversion (photocatalysis and solar cells) and data stora
 ge. These processes are very complicated and\, currently\, no single metho
 d can encompass all the involved phenomena in coupled electronic and nucle
 ar dynamics in the photo-excited functional molecule as well as the interp
 lay with the surroundings (e.g. a solvent). Using a variety of computation
 al approaches and experimental results\, we show how relatively minor vari
 ations in the molecular structure of Fe-N-heterocyclic carbene (NHC) compl
 exes lead to completely different excited-state relaxation of the initiall
 y excited singlet metal-to-ligand charge-transfer state\, and we shed ligh
 t on both the intra-molecular and molecule-to-solvent energy conversion pr
 ocess subsequent to photo-excitation of bi-metallic complexes.
