Abstract: A technique that combines organometallic catalysis with molecular imprinting of a polymer could lead to the production of highly active and selective enzyme mimics, according to chemists in Germany. Senior researchers Kurt Polborn and Kay Severin at Ludwig Maximilians University, Munich, have shown that the activity and selectivity of a ruthenium catalyst immobilized on a polymer support can be enhanced by using a transition-state analog as a template to imprint the polymer. The experiments revealed that the molecularly imprinted polymer enhanced the reaction rate by a factor of more than three compared with the control polymer.
