We have evaluated the strength of aromatic donor–acceptor interactions between dialkyl naphthalenediimide and dialkoxynaphthalene in non-polar environments. 1H NMR, UV-vis spectroscopy and isothermal titration calorimetry were used to characterise this interaction. We concluded that the strength of donor–acceptor interactions in heptane is sufficient to drive supramolecular assemblies in this and other aliphatic solvents.
