Abstract: Imprinted network polymers incorporating basic functional groups were developed to assess the binding and specificity of carboxylic acids. The binding affinities were determined using t-BOC-phenylalanine and 2-phenylbutyric acid as templates and substrates. Chiral. selectivity for the enantiomers of t-BOC-phenylalanine was found for polymers incorporating adenine or 2-aminopyridine functionality. Chiral selectivity in the case of (R)-(-)-2-phenylbutyric acid was found for the polymer utilizing N-(2-aminoethyl) methacrylamide as the functional monomer. Optimization of binding was achieved by changing polymerization conditions (thermal versus photochemical polymerization, monomer:template ratio) for t-BOC-phenylalanine imprinted polymers employing the N-(2-aminopyridine) methacrylamide monomer
