Avoiding the path of LIESST resistance
Nature Chemistry, Published online: 25 September 2026; doi:10.1038/s41557-026-02259-7Access to long-lived light-induced states in earth-abundant transition-metal chromophores is desirable but hard to achieve. Now, enhanced metal–ligand covalency has been shown to increase the lifetime of the photomagnetic high-spin state in a manganese photoswitch.
