We report three self-assembled iron complexes that comprised an anti-parallel open form (o-L ), a parallel open form (o-L ), and a closed form (c-L) of diarylethene conformers. Under kinetic control, Fe (o-L ) was isolated, which exhibited a dinuclear structure with diamagnetic properties. Under light-irradiation control, Fe (c-L) was prepared and exhibited paramagnetism and spin-crossover behaviour. Under thermodynamic control and in the presence of indispensable [Fe (Tp*)(CN) ] , Fe (o-L ) and Fe (c-L) transformed into tetranuclear Fe Fe (o-L ) , which exhibited complete spin-crossover behaviour at T =353 K.
我们报道了三种自组装铁配合物，它们由二芳基乙烯构象异构体的反平行开放形式（o-L）、平行开放形式（o-L）和封闭形式（c-L）组成。在动力学控制下，分离得到了Fe (o-L )，其呈现出具有抗磁性的双核结构。在光辐照控制下，制备了Fe (c-L)，其表现出顺磁性和自旋交叉行为。在热力学控制下且存在不可或缺的[Fe (Tp*)(CN) ] 时，Fe (o-L )和Fe (c-L)转变为四核Fe Fe (o-L )，其在T =353 K时表现出完全的自旋交叉行为。
