Controlled chiral electrochromism of polyoxometalates incorporated in supramolecular complexes†
Abstract
A three-component supramolecular system was constructed by combining host–guest recognition and electrostatic interaction for realization of induced circular dichroism of achiral polyanionic clusters in aqueous solution, while the induced chiral heteropoly blue was built and switched off by controlling the redox of the inorganic component via electrochemistry.
