Establishing the origin of Marcus-inverted-region behaviour in the excited-state dynamics of cobalt(III) polypyridyl complexes

Expanded use of earth-abundant chromophores for excited-state chemistry requires the ability to increase the energy content of excited states while simultaneously lengthening their lifetimes. It has now been shown that this goal can be achieved in Co(III)-based chromophores by virtue of their photophysical dynamics occurring in the Marcus inverted region.
