  • Interactions between reactive excited states of molecular photocatalysts and surrounding solvent can dictate reaction pathways, but are not readily accessible to conventional spectroscopic methods. Here the authors use diffuse X-ray scattering and theory to study the atomistic solvation dynamics of a photoexcited di-iridium complex in acetonitrile.

  • Photoinduced non-adiabatic intramolecular processes have important applications but their mechanisms are challenging to explore. Here the authors detect and assign vibrational wavepacket dynamics in a Fe carbene complex by ultrafast X-ray emission spectroscopy and X-ray scattering, resolving nuclear and electronic motion.

  • Photoinduced electron transfer in solvated molecular assemblies occurs on the ultrafast timescale before full electronic and geometric relaxation take place. Here Canton et al.monitor this out-of-equilibrium process in a donor–acceptor bimetallic assembly using an X-ray free-electron laser.

  • Using iron instead of the scarce ruthenium in light-harvesting complexes is challenging because iron complexes generally have short-lived excited states. Now an iron complex has been developed that has a long-lived excited state, which can lead to photo-induced electron injection into nanoporous TiO2 with a yield of 92%.
