Abstract

original image

Equal and opposite: A chiral surfactant molecule was used to induce high enantioselectivity in the transformation from the achiral phase of mercury sulfide, probably through binding of the surfactant thiolate groups to Hg ions in the forming crystal. The generation of truly chiral inorganic nanocrystals of tailored size and shape should be useful for many applications, such as enantioselective catalysis and sensing.
