Abstract

Although porphyrin containing metal organic frameworks (PCMOFs) have found applications in different important fields, for example catalysis, phototherapy, adsorption etc. the mechanism of water adsorption on these materials remains unknown. In this study we analyze adsorption-desorption data on three PCMOFs. It is shown that hysteresis on adsorption-desorption isotherms is caused probably by the structural deformations. The application of SAFT-VR model to describe the experimental data is in agreement with the in - situ DRIFT insight of the process showing that the affinity between water and studied MOFS decreases as follows: CaTCPP > MgTCPP > ZnTCPP > TCPP. Application of the in-situ DRIFT method leads to important information about the nature of water material interactions showing for example the creation of aqua complexes and hydrogen bonds.
