Poly(L‐glutamate) having amphiphilic side chains was designed as membrane materials for optical resolution of α ‐amino acids. Solvent‐ cast films of the poly(L‐glutamate) had a self‐ordered structure containing α‐helix of the poly(L‐glutamate). Optical resolutions of various amino acids were carried out through the thin membranes of the amphiphilic poly(L‐glutamate). Racemic mixtures of Tryptophan were completely separated through the membrane. Mechanism of the optical resolutions was investigated in terms of molecular recognitions of racemic Tryptophan by the ordered structure of the mambrane.
