New examples of light-induced excited spin state trapping (LIESST) in iron(II) spin-crossover systems
Abstract
Two new example are reported of (quantitative) light-induced excited spin state trapping (LIESST) in coloured polycrystalline iron(II) spin-crossover compounds, with practically infinite lifetime of the high spine state below a critical temperature (25 and 55K, respectively); LIESST now appears to be a common effect for iron(II) spin-crossover systems.
