Area of Interest
Broadly defined, research in our group involves the development of synthetic methodology, with particular applications to template-organized polymer materials. Potential applications are in the areas of chromatography, catalysis, bioÂmedical materials, molecular recognition and sensor technology. Two major areas of interest in our group are illustrated below.
Molecular Imprinting in 3-D Network Polymers: Network polymers can also be engineered for molecular recognition and catalytic properties using the method of molecular imprinting, shown below. To imprint a molecule, functionalized monomers are bound to a template molecule and the resulting complex is copolymerized with cross-linking monomers. Removal of the template leaves cavities in the polymer that are complementary in size, shape and chemical functionality to the template molecule. This rapidly developing technique provides polymeric artificial receptors, catalysts, organic zeolites, chromatographic supports and biosensors.
Molecular Imprinting in 2-D films: In order to obtain surface-imprinted and/or thin film materials, we are exploring an alternative strategy that involves molecular imprinting of alkanethiol self-assembled monolayer films (i.e. SAMs) on gold. The general strategy is illustrated below, for color-changing thin film for sensor applications. The third and/or fourth involve removal of the template, followed by the fifth step which is to verify and quantify binding and selectivity of the template by the imprinted film. Other variations on this theme are also being explored.
