We report the first examples of thiocyanate-based analogues of the cyanide Prussian blue compounds, M[Bi(SCN)], M = Fe, Cr, Sc. These compounds adopt the primitive cubic topology and show strict cation order. Optical absorption measurements show these compounds have band gaps within the visible and near IR region, suggesting that they may be useful for applications where light harvesting is key, such as photocatalysis. We also show that Cr[Bi(SCN)] can reversibly uptake water into its framework structure pointing towards the possibility of using these frameworks for host/guest chemistry.
我们报道了氰化普鲁士蓝化合物基于硫氰酸盐的类似物的首个实例，即M[Bi(SCN)]，其中M = Fe、Cr、Sc。这些化合物采用原始立方拓扑结构，并呈现出严格的阳离子有序性。光吸收测量表明，这些化合物在可见光和近红外区域内具有带隙，这表明它们可能在光捕获至关重要的应用中有用，例如光催化。我们还表明，Cr[Bi(SCN)]能够将水可逆地吸收到其骨架结构中，这表明这些骨架结构有用于主/客体化学的可能性。
