抄録

Molecularly imprinted polymeric membranes, bearing tetrapeptide derivative H-Asp(OcHex)–Ile-Asp(OcHex)-Glu(OBzl)-CH2-, were prepared during the membrane preparation (casting) process in the presence of print molecule Boc-L-Trp. The molecularly imprinted membranes thus obtained showed adsorption selectivity toward print molecule family, such as L-Arg, L-Lys, L-His, L-Asp, and L-Glu. The tetrapeptide derivative in the molecularly imprinted membranes preferentially recognized L-amino acid from racemic amino acids. Enantioselective electrodialysis was attained with the present membrane, and L-isomer was permeated in preference to D-isomer, while D-isomer was preferentially permeated by using concentration difference as a driving force for membrane transport. It was made clear that the optical resolution was attained by the molecularly imprinted polymeric membranes.
