Abstract: Halogen-substituted pillar[5]arenes exhibited hindered hydroquinone subunit flipping, enabling enantioseparation. An enantiopure conformer demonstrated a dissymmetric factor of 0.012 and an enantioselective binding ratio exceeding 1.92. Complexation with L-serine induced an... read more here.
