Breathing in metal-organic frameworks (MOFs) is an interesting and unique behavior of the material. However, there are still limited number of breathing MOFs. Herein, we present a series of new breathing MOFs comprising 2-D porous ladder like structure, which was stacked by hydrogen bonding to form 3-D network structure, Zn2(aipa)2(pillar) where, aipa = 5-Aminoisophthalic acid, pillar; bipy=4,4’-Bipyridine, tbpe=1,2-Di(4-pyridyl)ethylene, bpe=1,2-Bis(4-pyridyl)ethane, or abp=4,4’-Azopyridine. The framework structure is porous in the presence of solvent molecules, but the pore was totally closed upon removal of the solvent molecules. Interestingly, the closed pore was reversibly opened by exposure to solvent molecules such as Benzene, Pyridine, DMF, Acetonitrile and etc. We have studied for the control of pore open and close using not only solvent molecules but also gas pressure and external temperature. For demonstration of selective adsorption behavior, we have analyzed structure by single crystal X-ray diffraction, vapor/gas adsorption study and spectroscopic analysis. Therefore, it is expected that the materials can show interesting selectivity for adsorption of gas or organic vapor. Details of this work will be presented.
