摘要

Abstract We report a new achiral Cu host [Cu (bmb–bpy)(H 2 O)(OTf) 2](bmb–bpy= 6, 6′- bis [((1-methylbenzimidazol-2-yl) thio) methyl]-2, 2′-bipyridine) for the enantioselective and chemoselective recognition of chiral carboxylic acids. The binding of chiral carboxylic acids to [Cu (bmb–bpy)(H 2 O)(OTf) 2] produced an exciton-coupled circular dichroism signal; the linear discriminant analysis allowed the assignment of the absolute configuration, ...
