Abstract

original image

Pancakes in tubes: Coronenes, a class of planar π-conjugated molecules, organize in 1D structures when using single-walled carbon nanotubes (SWCNTs) as templates (see picture). Coronene columns with coaxial stacking in SWCNTs exhibit characteristic fluorescence spectra that significantly differ from those of isolated coronene molecules and three-dimensional crystals and that are related to their well-ordered 1D structure.
