Alternative molecularly imprinted polymeric membranes were prepared from a polystyrene resin bearing tetrapeptides consisting of D ‐amino acids or L‐amino acids. The membrane prepared from a DLDE derivative (H‐Asp(OcHex)‐Leu‐Asp(OcHex)‐Glu(OBzl)CH 2 ) consisting of D ‐amino acids and imprinted by Boc‐ D ‐Trp recognizes the D‐isomer in preference to the corresponding L ‐isomer and vice versa. The amino acid preferentially adsorbed by the membrane was selectively permeated by applying electrodialysis.
