Abstract: A molecularly imprinted polymer (MIP) was synthesized from the photoinduced polymerization of acrylamide and butylene diacrylate in the presence of L-2-chloromandelic acid (L-2-MDA) as template and was used as a highly selective separation materials for L-2-MDA. UV analysis showed the template L-2-MDA and functional monomer acrylamide formed complexes before polymerization. The structures of complexes were simulated by using Hyperchem and the binding energies were calculated as - 1.6437 x 10(4) J(.)mol(-1) and -4.2799 x 10(4) J(.) mol(-1) The binding capacity of MIP to L-2-MDA was higher than that of other analogs and the chiral separation factor alpha was 1.76. Scatchard analysis suggested that the MIP recognized L-2-MDA with two classes of binding sites, which is accordant with the two kinds of complex simulation models
Template and target information: L-2-chloromandelic acid, L-2-MDA
