Alternative molecularly imprinted polymeric membranes from a tetrapeptide residue consisting ofD‐ orL‐amino acids

摘要

AbstractAlternative molecularly imprinted polymeric membranes were prepared from a polystyrene resin bearing tetrapeptides consisting ofD‐amino acids or L‐amino acids. The membrane prepared from a DLDE derivative (H‐Asp(OcHex)‐Leu‐Asp(OcHex)‐Glu(OBzl)CH2) consisting ofD‐amino acids and imprinted by Boc‐D‐Trp recognizes the D‐isomer in preference to the correspondingL‐isomer and vice versa. The amino acid preferentially adsorbed by the membrane was selectively permeated by
