通过一个非手性配体和1D氰化铜链螺旋成功构建了一种新型的手性金属有机骨架:[Cu4(CN)4(L)2]n(1,L=四(3-吡啶氧亚甲基甲烷));铜(Ⅰ)和原位生成的氰基组装而生成的螺旋是左旋并且它使得金属有机框架具有手性。这是首例通过半刚性四面体配体多变的构像诱导合成独特的手性金属有机骨架化合物。此外还研究了该化合物的手性、热稳定性以及介电性质。
A novel chiral metal-organic framework has been successfully constructed by using a non-chiral ligand and a 1D copper cyanide chain: [Cu4 (CN) 4 (L) 2] n Methylene methane)); the copper formed by the copper (I) and the in situ generated cyano group is levorotatory and it renders the metal-organic framework chiral. This is the first case of a unique chiral metal-organic framework compound induced by conformational changes induced by semi-rigid tetrahedral ligands. In addition, chirality, thermal stability and dielectric properties of the compound were also investigated.
