How low can you go? An Fe(II) (4) square was prepared by self-assembly and exhibits both thermally induced and photoinduced spin crossover from a system with four high-spin (HS) centers to one with two high-spin and two low-spin (LS) centers. The spin-crossover sites are located on the same side of the square, and the spin transition and magnetic interactions (see picture) are synergistically coupled.
你能降到多低?通过自组装制备了一个Fe(II) (4) 正方形,它展现出从一个具有四个高自旋(HS)中心的体系到一个具有两个高自旋和两个低自旋(LS)中心的体系的热诱导和光诱导自旋交叉。自旋交叉位点位于正方形的同一侧,并且自旋转变和磁相互作用(见图)是协同耦合的。
