A new Cs-gamma-CD-MOF material obtained in colourless large crystals and with a three-dimensional porous structure containing coordinated by cesium ions and gamma-cyclodextrin was synthesised by an improved vapour diffusion method. The chemical formula of the Cs-gamma-CD-MOF material was C24H34CsO20, with the I-4 space group. Compared with the traditional solvent vapour diffusion method (7 days), this method is advantageous for rapid crystal formation (1 day). Simultaneously, the drug adsortion capacity of gamma-CD and Cs-gamma-CD-MOFs for myricetin was compared and the results indicated that ...
