A 3D Hofmann-like metal-organic framework has been prepared which contains a 2,1,3-benzothiadiazole-based pillaring ligand. Encapsulation of a polycyclic aromatic hydrocarbon, chrysene, within the pore structure leads to a new pathway to multi-step spin crossover behaviour in which the observed two-step spin transition arises due to the presence of multiple site environments associated with local guest positional effects within the host lattice.
已制备出一种类似霍夫曼结构的三维金属有机框架，其包含基于2,1,3-苯并噻二唑的支柱配体。在孔结构中封装多环芳烃屈，导致了多步自旋交叉行为的新途径，其中观察到的两步自旋转变是由于主体晶格内与局部客体位置效应相关的多个位点环境的存在。
