A new type of clay column particles was prepared, in which a hectorite layer (similar to 0.1 mu m thickness) covered uniformly the surface of amorphous silica particles with an average radius of 5 mu m (ref. Okada et al., The Journal of Physical Chemistry C, 116, 21864-21869 (2012)). The hectorite layer was fully ion-exchanged with Delta-[Ru(phen)(3)](2+) (phen = 1,10-phenanthroline) ions by being immersed in a methanol solution of Delta-[Ru(phen)(3)](ClO4)(2) (1 mM). The modified silica gel particles thus prepared were packed into a stainless steel tube (4 mm (i.d.) x 25 cm) as a high-performance liquid chromatography column. Optical resolution was achieved when the racemic mixtures of several metal complexes or organic molecules were eluted with methanol. In the case of tris(acetylacetonato) ruthenium(III) ([Ru(acac)(3)]), for example, the Lambda- and Delta-enantiomers gave an elution volume of 2.6 and 3.0 mL, respectively, with the separation factor of 1.2. The total elution volume (5 mL) was nearly one-tenth for the previously reported column of the same size (RU-1 (Shiseido Co., Ltd.)) packed with the spray-dried particles of synthetic hectorite (average radius 5 mu m) ion-exchanged by the same Ru(II) complexes. |
