Method for preparing porous europium-manganese coordination polymer material and application thereof

The invention discloses a method for preparing a porous europium-manganese coordination polymer and an application thereof. The porous europium-manganese coordination polymer is a coordination compound in the following chemical formula: [Eu(CAM)(HCAM)2Mn2(H2O)7].7H2O, wherein CAM and HCAM respectively are obtained from 4-hydroxy-2,6-cinchomeronic acid, from which three hydrogen ions and two hydrogen ions are removed. The preparation method of the coordination polymer comprises the steps of mixing Eu(NO3)3.6H2O with 4-hydroxy-2,6-cinchomeronic acid according to the mol ratio of 1:3 and adding to DEF; reacting for 72 hours at 90 DEG C to obtain the coordination compound, namely Eu(H2CAM)3.5H2O; mixing the Eu(H2CAM)3.5H2O with MnCl2.4H2O according to the mol ratio of 1:3, adding to water to react for 72 hours at 120 DEG C; and cooling, filtering, standing and washing by a program to obtain the product. The coordination polymer contains a one-dimensional duct; the mixture of methanol and ethanol has a good separating effect at normal temperature and normal pressure, and has good cycle performance. The coordination polymer can separate fatty alcohol compounds without activation at normal temperature and normal pressure, and has good cycle performance. The coordination polymer has great significance in the aspects of preparation of separate materials and mechanism research.
