Abstract
Photo–cured DNA–4–vinylbenzyltrimethylammonium (DNA–VBTMA) complex membranes were obtained by UV curing of DNA–4–vinylbenzyltrimethylammonium complex membranes and photoinitiator, 2–hydroxy–2–methyl–1– phenyl–1–propanone (HMPP). The membrane with arbitrary charged state was obtained by adjusting the feed composition in membrane preparation process. The positively and negatively charged membranes showed optical resolution ability; in other words, those two types of membrane transported D–Lys in preference to L–Lys from racemic mixture of Lys. The permselectivity toward D–Lys reached 1.52. The membranes showing chiral separation ability selectively incorporated the D–isomer of Lys into them. In the present study, the permselectivity was mainly expressed by the affinity between D–Lys and membranes.
