Based on the presented statistics, it is a common practice to exchange the solvent with another low surface tension solvent, or low boiling point solvent, then evacuate and/or evaporate the solvent. Consequently, the volatile exchanged-solvent can smoothly leave the pores without damaging the framework. Indeed, some MOFs may not be stable in all the volatile organic solvents, in other words, the MOF should be insoluble in the exchange-solvent and retains its crystalline integrity. In addition, to achieve a complete solvent exchange, the MOF is often soaked in the solvent for several hours or even days, while the solvent is repeatedly replaced with fresh solvent to maximize the exchange efficiency. As was pointed previously, in this work, if the MOF was just washed with a different solvent, then it was also considered as solvent exchanged. Because, for some MOFs, the solvent-exchange can be achieved within minutes, as reported by Ma et al. for the MOF UMCM-9.
