AI 中文摘要
金属-有机框架（MOFs）被广泛探索用于气体分离、催化或能量存储，但其与其他电子功能材料的集成在很大程度上仍未得到探索。在此，我们将层状霍夫曼型自旋交叉（SCO）MOF {FeII(pyS2Et)2[PtII(CN)4]} 集成到电子纳米器件中，以控制二维（2D）量子材料的性质。我们的分子方法利用了SCO层状材料的刺激响应特性作为可切换的构建模块。我们展示了通过热和光诱导自旋跃迁产生的应变，对SCO与2D量子材料（少层石墨烯、磁性CrSBr、超导NbSe2）界面构成的范德华异质结构中的电子输运进行选择性调制。在石墨烯中，电导率可通过光选择性切换。在基于CrSBr双层的自旋阀中，MOF触发了磁滞现象（在原始CrSBr中不存在），并实现了可调的非易失性零场存储。在NbSe2中，光调制了超导临界电流和转变温度。这些结果确立了层状刺激响应性SCO MOFs作为2D量子材料的活性分子控制元件，提供了一条通过应变介导控制电子、磁性和超导功能的途径，并将基于MOF的架构从传统的多孔材料应用扩展到多功能电子学和自旋电子学。
英文摘要
Metal-organic frameworks (MOFs) are widely explored for gas separation, catalysis or energy storage, yet their integration with other electronically functional materials remains largely unexplored. Here, we integrate the layered Hofmann-type spin-crossover (SCO) MOF {FeII(pyS2Et)2[PtII(CN)4]} into electrical nanodevices to control the properties of two-dimensional (2D) quantum materials. Our molecular approach exploits the stimuli-responsive nature of SCO layered materials as switchable building blocks. We demonstrate selective modulation of the electronic transport in van der Waals heterostructures interfacing SCO with 2D quantum materials (few-layer graphene, magnetic CrSBr, superconducting NbSe2) through the strain induced via thermal and light-induced spin transitions. In graphene, the conductivity is selectively switched by light. In spin-valves based on CrSBr bilayers, the MOF triggers magnetic hysteresis (absent in pristine CrSBr) and enables tunable non-volatile zero-field memory. In NbSe2, light modulates the superconducting critical current and transition temperature. These results establish layered stimuli-responsive SCO MOFs as active molecular control elements for 2D quantum materials, providing a route to strain-mediated control of electronic, magnetic, and superconducting functionalities and extending MOF-based architectures beyond traditional porous-matter applications towards multifunctional electronics and spintronics.
