The Cover Feature shows how guest‐inclusion‐triggered molecular spin switching at room temperature is realised in nanoporous Fe 2 (azpy) 4 (NCS) 4 when its pores are flooded with iPrOH or EtOH guest molecules under pressure. A high density and mobility of guest molecules within the framework pores ensures the fragile structure withstands pressures up to a few GPa. Guest‐to‐ligand interactions trigger high‐spin (paramagnetic) to low‐spin (diamagnetic) switching at the majority of metal‐ion cores, thus rendering potential pressure sensor or actuator capabilities.
