Abstract
The invention discloses a preparation method of a supramolecular crystal material based on crown ether-Keggin type polyacid, and belongs to the technical field of preparation of polyoxometallate compounds. The preparation method comprises the steps of dissolving Keggin type polyoxometallate in an acetonitrile solution, then adding an alkali metal element, heating to the temperature of 60-80 DEG C, then adding supramolecular crown ether for reaction, filtering after the reaction is finished, taking filtrate, volatilizing a solvent to obtain crystals, and then carrying out suction filtration, washing and drying to obtain the supramolecular crystal material based on crown ether-Keggin type polyacid. The preparation method is simple, the yield is high, and most importantly, a stable crystal structure is formed.
