LIQUID–FREE MECHANOCHEMICAL PREPARATION OF RARE EARTH METAL ORGANIC FRAMEWORKS

摘要

Metal organic frameworks (MOFs) are hybrid inorganic-organic crystalline materials with intrinsically high porosity. MOFs have attracted significant attention due to applications as luminescent materials, advanced gas absorbers, sensors, etc.[1] Rare earth based MOFs are best known for their excellent luminescence properties. Although the first report on mechanochemical synthesis of organic compounds dates back to 2002 [2], the synthesis of MOFs using this approach was not reported until 2006.[3] Since then there has been intense research activity on MOFs synthesis using this approach.[1] Till 2012, all the reported mechanochemical synthesis of MOFs involved liquids which were either added externally to assist grinding or were generated in-situ as by-products.[4]
