摘要
Measuring the Pfeiffer effect of the addition of bovine serum albumin (BSA) as an optically active environment to a tris(oxalato) cobaltate(III) anion, [Co(ox)(3)](3-), we found that the Lambda-enantiomer of the complex anion is enriched in 5 or 10% dioxanewater solutions but the Delta-enantiomer is concentrated in aqueous solution, where the enantiomeric excess is 72% (Lambda rich) in 10% dioxanewater solution.
