Abstract

Abstract The review presents several families of spin crossover (SCO) active Fe(II) coordination compounds with photoactive N-donor heterocyclic ligands, in which the photoinduced structural changes can activate reversible change of spin state and thus control magnetic properties under isothermal conditions. Detailed description of structural, spectral, and magnetic behavior for selected examples of photoisomerizable coordination compounds are provided. From the application point of view, light is an excellent tool to control SCO properties. The first and best known approach called Light Induced Excited Spin State Trapping (LIESST) has a significant technological limitation due to low temperatures (< 120 K) required for the trapping and existence of photoexcited metastable states. The second and more elegant approach known as Ligand-Driven Light-Induced Spin Crossover (LD-LISC) seems to be a very suitable strategy utilizing light-induced structural changes to control the spin. Isomerization of photoswitchable groups, such as azobenzenes or stilbenes, can cause reversible transformation between two isomeric forms after exposition to selective wavelengths at ambient temperature. A very recent third approach, the Guest-Driven Light-Induced Spin Crossover (GD-LISC) effect employing the photoisomerizable guest molecules to control the spin state has also been introduced.
Fe(II)配合物和配位聚合物中的光和热诱导SCO效应
摘要综述了几种具有光活性N-供体杂环配体的自旋交叉(SCO)活性Fe(II)配位化合物家族,其中光诱导的结构变化可以激活自旋状态的可逆变化,从而控制等温条件下的磁性能。提供了可光异构化配位化合物的选定实例的结构、光谱和磁性行为的详细描述。从应用的角度来看,光是控制SCO特性的极好工具。第一种也是最为人所知的方法称为光诱导激发自旋态捕获(LIESST),由于捕获和存在光激发亚稳态所需的低温(<120K),具有显著的技术限制。第二种也是更优雅的方法,称为配体驱动的光诱导自旋交叉(LD-LISC),似乎是一种非常合适的策略,利用光诱导的结构变化来控制自旋。光可切换基团,如偶氮苯或二苯乙烯的异构化,在环境温度下暴露于选择性波长后,可以导致两种异构形式之间的可逆转变。最近的第三种方法,利用可光异构化的客体分子来控制自旋状态的客体驱动光诱导自旋交叉(GD-LISC)效应也被引入。
