How much should we switch? Two Fe II 4 L 4 tetrahedral capsules were shown to undergo thermally induced spin crossover (SCO). Guest binding to one of these capsules was observed to affect the thermodynamics of its SCO in solution, leading to different spin transition temperatures between the empty host (blue) and the host–guest complex (red). HS: high spin; LS: low spin.
