Construction of Bis(zinc porphyrin) and Its Application for the Direct Determination of Absolute Configuration of Monoalcohols

Abstract

Construction of a novel achiral host molecule system utilizing meso-carbon bridged zinc porphyrin dimers, bis(zinc porphyrin), is presented. These dimers that adopt a pseudocofacial conformation in the absence of a guest molecule can effectively bind not only strong amino-containing ligands but also relatively weak ligans such as alcohols and ethers over room temperatures. The direct determination of the absolute configuration of monoalcohols at low concentrations and room temperature based on the CD exciton chirality method can now be realized utilizing the bis(zinc porphyrin).
