Spin-crossover metal complexes are highly promising magnetic molecular switches for prospective molecule-based devices. The spin-crossover molecular photoswitches developed so far operate either at very low temperatures or in the liquid phase, which hinders practical applications. Herein, we present a molecular spin-crossover iron(II) complex that can be switched between paramagnetic high-spin and diamagnetic low-spin states with light at room temperature in the solid state. The reversible photoswitching is induced by alternating irradiation with ultraviolet and visible light and proceeds at the molecular level.
自旋交叉金属配合物是很有前途的磁性分子开关，可用于有前途的基于分子的设备。到目前为止开发的自旋交叉分子光开关要么在非常低的温度下工作，要么在液相中工作，这阻碍了实际应用。在此，我们展示了一种分子自旋交叉铁(II)配合物，它可以在室温下在固态中通过光在顺磁高自旋和抗磁低自旋状态之间切换。可逆光致开关通过交替辐照紫外光和可见光诱导，并在分子水平上进行。
