Bis(zinc porphyrin) as a CD-sensitive bidentate host molecule: direct determination of absolute configuration of mono-alcohols

Abstract

A facile and direct protocol to determine the absolute configurations of chiral mono-alcohols without analyte derivatization can now be realized using a novel circular dichroic (CD)-sensitive bis(zinc porphyrin) BP1 host system. The binding of mono-alcohols to BP1 should be greatly enhanced by the simultaneous double coordination of the hydroxyl group to the two central metals of the porphyrin subunits.
