A functional nickel(II) complex carrier for up-hill transport of a histidine derivative by pH-induced affinity switching
Abstract
The square-planar nickel(II) complex of 6,6-bis(4-hexylbenzoylamino)-2,2′-bipyridine mediates up-hill transport of carbobenzoxyhistidine (Cbz-His) across an organic liquid membrane by affinity switching of the axial coordination of the imidazole unit of Cbz-His to the metal centre.
