Abstract:

Chiral metal-organic frameworks(MOFs) have recently received great attention in enantioselective catalysis and chiral separation areas because of their unusual properties such as high surface areas, diverse topologies and excellent chemical and thermal stability. A three-dimensional chiral MOF [Mn3(HCOO)4·(D-Cam)] n with homochiral chain was used as stationary phase for column A(30 m×250 μm i.d.) and column B(5 m×75 μm i.d.) in gas chromatography. We investigated the coating properties of stationary phase by scanning electron microscope(SEM) on capillary column inner wall and the thermal stability by thermogravimetric analysis(TGA). Some racemates, alkanes and isomers were used as targets for separation on column B. The experimental results showed that the stationary phase also possessed good separation ability toward these organic compounds.

Key words: Metal-organic framework, Racemate, Stationary phase, Capillary column, Gas chromatography
