The Cover Feature shows how guest‐inclusion‐triggered molecular spin switching at room temperature is realised in nanoporous Fe₂(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.

封面功能：室温下纳米多孔宿主-客体框架结构中的压力诱导自旋交叉（ChemPlusChem 1/2021）

封面功能显示了纳米多孔Fe ₂（azpy）₄（NCS）₄在压力下充满iPrOH或EtOH客体分子时，如何在室温下实现客体包含物触发的分子自旋转换。客体分子在骨架孔中的高密度和迁移性确保了其脆弱的结构能够承受高达数GPa的压力。客体与配体之间的相互作用会在大多数金属离子芯处触发从高旋转（顺磁性）到低旋转（反磁性）的切换，从而具有潜在的压力传感器或执行器功能。有关更多信息，请参见B. Vatsha，R。Goliath和G. Hearne的来文。
