Glowing together: An efficient red-light-emitting system has been created in polar water media based on the aggregation of donor-acceptor molecules. In the THF/water mixture, the emission was quenched when a small volume of water was used, whereas it was recovered and enhanced upon aggregate formation with a large water volume.
In a polar aqueous environment, a series of triphenylamine-based donor–acceptor-type dyes showed efficient light emission upon the formation of aggregates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
