Counterion-dominating chirality transfer between chiral and achiral polyoxometalates

Abstract

We show that chirality transfer from chiral polyoxometalates to achiral polyoxometalates can occur in aqueous solution with unexpected selectivity of surrounding counterions. In comparison with sodium ions, protonated dimethylammonium counterions play a critical role in shortening the inter-cluster distance, thus promoting the efficiency of chirality transfer.
