We report a high-efficiency photoinduced phase transition in a spin-crossover complex [FeL (CN)2] · H2O (where L is a N3 O2 Schiff-base macrocyclic ligand). A single-shot laser pulse (8 ns duration) is applied to induce the phase transformation, exhibiting molecular-structural, chromatic, and magnetic changes inside a thermal hysteresis loop (216 K). The condensation of long lifetime photoexcited high-spin sites accounts for the cooperative photoexcitation process.
