以去叔丁基硫杂杯[4]芳烃与Mn(Ⅱ)为研究对象,通过改变体系溶剂分别得到了2个四核化合物Mn4(T4A)2(1)和Mn4(T4A)2(DMF)2(2)(T4A=thiacalix[4]arene).当反应溶剂为氯仿和甲醇的混合溶剂时,形成的是以四核锰为结构单元的二维“笼目”(Kagomé)状超分子化合物1,而当反应溶剂为N,N-二甲基甲酰胺(DMF)和甲醇的混合溶剂时,得到的是格子状二维超分子互穿的三维结构化合物2.化合物1具有很大的溶剂占有空隙,是一个潜在的多孔材料,而化合物2是一个紧密堆积的拓展结构.

In this paper, two tetranuclear compounds Mn4 (T4A) 2 (1) and Mn4 (T4A) 2 (DMF) were obtained by changing the solvent of the system. (T4A = thiacalix [4] arene). When the reaction solvent is a mixed solvent of chloroform and methanol, a two-dimensional “Kagomé” Molecular compound 1, and when the reaction solvent is a mixed solvent of N, N-dimethylformamide (DMF) and methanol, a three-dimensional lattice compound 2 is obtained which is interpenetrated by two-dimensional supramolecules. Compound 1 has a large Of the solvent occupy the voids, is a potential porous material, and compound 2 is a close-packed structure of the expansion.
