Abstract: Methacrylic acid (MAA) and 2- (trifluoromethyl)acrylic acid (TFMAA) were used to prepare molecularly imprinted polymers exhibiting diastereoselectivity for cinchona alkaloids. Fluorescent spectra of the cinchona alkaloid exhibit a characteristic shift through binding to these polymer particles, originating most likely from the highly acidic residues in the imprinted polymers acting as a proton donator. Our results show that TFMAA based imprinted polymers can be used as polymer reagents for quantitating the cinchona alkaloid bound to the polymers without bound/free separation
