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.
Paul Lickiss, Professor of Organometallic Chemistry, is interested in the chemistry of main group compounds, particularly organosilicon compounds. Research is currently focused in several areas. Read more here
