The synthesis and characterization of four enantiopure polyoxometalate- cored dendrimers, which contain n-propyl and epoxy groups, based on electrostatic interactions between enantiopure dendritic quaternary ammonium ions and an a chiral trianionic POM has been reported. The optical and chiroptical properties of the n-propyl-terminated POM-cored dendrimers have been demonstrated in solution by UV/Vis spectroscopy, circular dichroism (CD) and vibrational circular dichroism (VCD) spectroscopy, and fluorimetry. The solution CD, UV/Vis and VCD data indicate a significant induced optical activity in the POM cluster. The appropriate elaboration of optimized dendritic structures enabled the use of a range of POM species, and represented a promising approach to efficient, recoverable, and highly enantioselective dendritic POM future catalysts.
