具有多自旋态的自旋交叉（SCO）材料由于在多开关和高阶数据存储方面的潜在应用而引起人们的特别兴趣。本文中，在三维Hofmann型金属有机骨架[Fe（4-abpt）{Au（CN）2}2]·2DMF·EtOH（4-abpt = 4-amino-3，5-bis（4-pyridyl）-1，2，4-triazole）中揭示了前所未有的不对称七/八步SCO行为，这代表了SCO领域中的最高步骤。此外，通过混合[Au（CN）2]-和[Ag（CN）2]-单元形成分子合金首次被探索作为多步SCO材料的策略。
Spin-crossover (SCO) materials with multiple spin states have attracted special interest for their potential applications in multi-switches and high-order data storage. Herein, an unprecedented asymmetric seven-/eight-step SCO behavior is revealed in a three-dimensional Hofmann-type metal–organic framework [Fe(4-abpt){Au(CN)2}2]·2DMF·EtOH (4-abpt = 4-amino-3,5-bis(4-pyridyl)-1,2,4-triazole), which represents the highest step in the SCO field. Moreover, the formation of a molecular alloy by mixing [Au(CN)2]− and [Ag(CN)2]− units is explored as a strategy towards multi-step SCO materials for the first time.
