Enantiopure 1,1‘-Binaphthyl-Based Polyoxometalate-Containing Molecular Hybrids

The first chiral molecular hybrids based on covalently linked polyoxometalate clusters and enantiopure 1,1‘-binaphthyl units have been prepared. Their structures have been confirmed by 1H NMR, FTIR, and ESI-MS measurements. Such hybrids show moderate chiroptical behavior in solutions, and Cotton effects are observed up to 450 nm, indicating chiral extension from the binaphthyl core to the cluster-containing π-conjugated arms.
