  • Singlet fission is a promising carrier multiplication process, where a singlet exciton is split in two triplet states. Here the authors propose an oxygen-assisted two-step mechanism for singlet fission accounting for ~ 40% triplet quantum yield in dilute solutions where the single-step mechanism is inactive.

  • Pump–probe measurements conventionally achieve femtosecond time resolution for X-ray crystallography of reactive processes, but the measured structural dynamics are complex. Using coherent control techniques, we show that the ultrafast crystallographic differences of a fluorescent protein are dominated by ground-state vibrational processes that are unconnected to the photoisomerization reaction of the chromophore.
