Abstract

The silicon-oxygen bond is prevalent in well-known porous materials including zeolites, organosilicas, and POSS hybrids, but metal-organic frameworks (MOFs) incorporating Si-O bonds are rare. This is despite advantageous properties of siloxanes including low toxicity, low chemical reactivity and thermal stability. In this work, highly-connected organosilicon polycarboxylic acids are described and applied in the construction of MOFs. The polycarboxylic acids themselves crystallize as unusual interpenetrated 3D hydrogen-bonded frameworks. Reaction of the acids with a range of metal salts gives rise to a wide range of MOFs often with unusual topology.  Their synthesis, structures and properties will be described.
