Chiral Organization of Tetraphenylethylenes Mediated by Multivalent Hydrogen Bonding

Abstract

Tetraphenylethylene (TPE)-based chiral supramolecular assemblies with chiroptical activity were constructed via the cooperative polymerization of multivalent hydrogen-bonding monomers. By employing these fluorescent supramolecular assemblies as energy donors and introducing Nile Red (NiR) as the acceptor, an aqueous artificial light-harvesting system was successfully established with the assistance of cetyltrimethylammonium bromide (CTAB).
