Abstract: Microwave assisted synthesis may be used to produce water-repellent metallic organic frameworks (MOFs) molecules. The water-repellent MOFs contain non-polar functional groups, such as a trifluoromethoxy group, which has a strong water repellent effect. The water-repellent MOF, when exposed to water vapor for one week does not result in a significant X-ray power pattern change. The water-repellent MOFs may be suitable as an adsorbent in many industrial applications, such as gas chromatography.
