Abstract
The inclusion properties of a calixarene-based porous material were studied to study the adsorption and the desorption of CCl4, CHCl3, and H2O in the zeolite-like structure. Uptake and release processes were studied both by time-resolved powder x-ray diffraction and by TGA to obtain structural and kinetic information. The selected guests are able to enter the structure with an increase in the host cell vol. and with time-dependent diffusivity coeffs. CHCl3 mols. act as a permanent porosity switch promoting a phase transition to nonporous triclinic form.File in questo prodotto:
