Molecular recognition of procainamide-imprinted polymer
Abstract
A procainamide-specific polymer was prepared by molecular imprinting using methacrylic acid as a functional monomer.
It was showed that the imprinted polymer was capable of recognizing the functional difference of amide group and ester
group between procainamide and procaine. The procaine-imprinted polymer was also prepared using the same monomer in
the same molar ratio of monomer/template, however, it had no such ability. The different molecular imprinting effect of the
two molecules showed that changing an amide group for an ester made quite a difference in terms of hydrogen acceptor. The
role of the functional groups of the templates in the formation of complementary interacting sites in the polymer and the
role of the corresponding interacting sites in the subsequent molecular recognition, was carefully discussed. Accordingly, the
mechanism of molecular recognition of this system was proposed. Acrylamide was also used as a functional monomer for the
preparation of procainamide-imprinted polymer to be compared with methacrylic acid. It was confirmed that hydrogen bond
played an important role in the selectivity of the imprinted polymers. © 2001 Elsevier Science B.V. All rights reserved.
