In this study, we successfully synthesize cationic/neutral/anionic inverse-Hofmann-type spin crossover (SCO) frameworks with 1,1,2,2-tetrakis(4-(pyridine-4-yl)phenyl)-ethene ligand by means of cyanometallic charge engineering strategy. The cationic and neutral frameworks exhibit single-step thermally induced spin transition behaviors, while the SCO capability of anionic framework can be aroused by partial desolvation. This strategy provides a new idea to construct ionic SCO frameworks and extends the toolkit for SCO materials.
在本研究中，我们通过氰基金属电荷工程策略，成功地合成了具有1,1,2,2-四（4-（吡啶-4-基）苯基）乙烯配体的阳离子/中性/阴离子反霍夫曼型自旋交叉（SCO）框架。阳离子和中性框架表现出单步热诱导自旋转变行为，而阴离子框架的SCO能力可通过部分去溶剂化激发。该策略为构建离子型SCO框架提供了新思路，并扩展了SCO材料的工具库。
