| Supramolecular self-assembly allows the construction of materials based on geometry of the components. In the past, synthetic chemists have harnessed this process in order to create a wide variety of periodic frameworks. Periodicity in these materials can be precluded either geometrically or kinetically to result in amorphous coordination polymers and gels. Ligand exchange reactions with metal clusters and polycarboxylates can form coordination polymer gels (CPGs) in one step under appropriate conditions. Clusters based on Fe3O(O2CCH3)6(H2O)3, with an assortment of metals, have been shown to form gels with an array of polyfunctional carboxylic acids. Furthermore, solvent can be removed from these gels, under ambient conditions or under supercritical CO2, creating xerogels and aerogels. Rheological and Mechanical properties of the resulting wet and dried gels have been investigated. |
