The application of chiral ligand containing metal complexes and ionic compounds to promote asymmetric catalytic reactions has become a very powerful strategy for synthesizing chiral compounds. More recently, chiral supramolecular systems have also attracted much attention. Though a variety of chiral supramolecular metal complexes have been studied for catalysis, only a few examples are reported in the literature using chiral supramolecular metal nanoparticle (M-NP) catalysts.To this end, we designed water-soluble, biocompatible, self-assembled rosette nanotubes (RNTs), which show supramolecular chirality in solution. We found that this chirality is preserved even after formation of palladium (Pd) NPs on the surface (Figure 1). This intriguing result encouraged us to investigate asymmetric reactions using our chiral supramolecular Pd NPs/RNTs composite catalyst. This paper will describe: (i) the characterization of the catalyst by UV-Vis and circular dichroism spectroscopy as well as scanning electron and transmission electron microscopy, and (ii) preliminary results obtained from our asymmetric catalysis studies.
