Abstract: Regarding the molecular imprinting principle. the selection of the functional monomer is of great importance to realize molecularly imprinted polymers with high affinity and selectivity. In noncovalent molecular imprinting. methacrylic acid (MAA) has been demonstrated as the most useful functional monomer. Recently, we have introduced a new functional monomer, 2-trifluoromethyl)acrylic acid (TFMAA), on the rationale that a more acidic functional monomer could be preferable for imprinting basic template molecules. Agrochemicals and drugs with high basicity were examined as test template molecules, and the use of TFMAA resulted in imprinted polymers with high affinity and selectivity. It was found that TFMAA shows 'taste" in template molecules that is different from MAA's. Other research activities on molecular imprinting performed in our laboratory will be also mentioned
