基于四(3-吡啶氧亚甲基)甲烷及氰化铜螺旋链手性金属有机骨架化合物的合成及其性质研究(英文)

Synthesis of Chiral Metal-Organic Framework and Study of Its Properties Based on Tetrakis(3-pyridyloxymethylene)methane and Helical CuCN Chains

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 homochiral metal-organic framework is successfully constructed by an achiral ligand and 1D helical EuCN chains： [Cua（CN）4（L）2]n （L=tetrakis（3-pyridyloxymethylene）methane） （1）; the helixes assembled by copper（I） and CN groups in situ generated are left-handed and transform the framework to chiral. This is the first example of chiral MOFs induced by flexible conformation of semigrid tetrahedral ligand. In addition, the chiral property of bulk products is confirmed by VCD spectra, the thermal stability and dielectric properties are also investigated. CCDC： 921046.
