Smart coumarin-tagged imprinted polymers for the rapid detection of tamoxifen.

A signalling molecularly imprinted polymer was synthesised for easy detection of tamoxifen and its metabolites. 6-Vinylcoumarin-4-carboxylic acid (VCC) was synthesised from 4-bromophenol to give a fluorescent monomer, designed to switch off upon binding of tamoxifen. Clomiphene, a chlorinated analogue, was used as the template for the imprinting, and its ability to quench the coumarin fluorescence when used in a 1:1 ratio was demonstrated.

Molecularly Imprinted Polymers for Catalysis and Synthesis.

The area of biomimetic catalysis based on molecular imprinted polymers has progressed considerably over the last two decades, with research efforts focused on developing catalysts for challenging reactions and on understanding the key factors in template structure and polymer morphology that influence efficiency and selectivity. Recent advances and significant achievements in the field presented in this chapter are organized according to four topics: hydrolytic reactions of challenging substrates, oxidase mimics, metallo-enzyme mimics, and polymers that display unusual reactivity, such as in the case of reactions for which enzymes don't exist, such as Diels-Alder and Kemp elimination. For each theme, significant examples for recent literature are presented and discussed.
