Abstract

Slow relaxation : Exergonic high‐spin→low‐spin relaxation after photoexcitation has been found to be exceedingly slow in a class of iron(II) complexes with hexadentate imine ligands. The thermal activation barriers that arise between the quintet‐ and singlet‐spin manifolds are the highest ever recorded for spin crossover of isolated molecules in free solution.
