A one-dimensional n-type semiconducting nanotube is formed by the self-assembly of a naphthalenetetracarboxylic acid diimide-lysine bolaamphiphile. In their Communication on page 7688 ff., J. R. Parquette and co-workers show how the nanotubes aggregate into a monolayer membrane that curves into rings, which then stack into tubes. Solid-state NMR studies show that there is exceptional conformational homogeneity among the constituent molecules that comprise the nanotubes, leading to efficient energy migration within the assemblies.
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.
