Abstract

original image

Blue rinse: A hybrid surfactant that comprises a hexavanadate cluster and two C18 alkyl chains shows unexpected blue luminescence (see picture). The luminescence arises from the interaction between the counterions and the hexavanadate clusters, and varies with the type of counterions. This behavior was confirmed by studying the self-assembly of the hybrids with various counterions in different solvents.
