Fabrication of a capillary column coated with the four-fold-interpenetrated MOF Cd(D-Cam)(tmdpy) for gas chromatographic separation

Abstract

The diverse structures and unique properties of metal organic frameworks (MOFs) are attractive attributes for analytical application. In this work we apply the four-fold-interpenetrated MOF Cd(D-cam)(tmdpy) as the coating material in capillary columns for gas chromatographic separation of aromatic hydrocarbons (ether, acid and alcohol), linear alkane hydrocarbons (aldehyde, acid and ether). The good thermal and chemical stabilities as well as the provision of suitable host-guest interaction sites within the interpenetrating frameworks make it an excellent chromatographic stationary phase for gas separation.
