The host–guest composites of Hofmann‐type iron(II) spin‐transition (ST) porous coordination polymers incorporating guest molecules show guest‐dependent ST behavior in accordance with the respective guest species, which may be a gas, solvent, halogen, or organic molecule. The guest also works as a chemical stimulant to switch the spin state of the host between high and low spin at room temperature. In this review, we discuss guest properties including size, shape, flexibility, chemical properties, and pore loading content, which impact the spin states of the host framework and the ST behavior exhibited by the host–guest composites.
