報告內容簡介：

Zeolitic imidazole framework-8 (ZIF 8) is a promising metal-organic framework (MOF) for the storage, separation, and detection of gases at room temperature and atmospheric pressure. Intermolecular interactions between ZIF-8 and adsorbed gas molecules which perform an important role in the adsorption process, can be attributed to non-covalent bonds such as van der Waals forces. The resonance frequency of these bonds falls in the terahertz (THz) frequency band. Skeletal vibration of organic linkers also occurs in this band and seems to be affected by adsorption. Previous studies using DFT calculations suggest that the frequency of open-gate motion exists at the range of 1 to 2 THz. Thus, gas adsorption onto ZIF-8 can be observed by monitoring changes in its terahertz transmission spectrum as a function of gas exposure.
