Charge‐transfer (CT) assemblies of aromatic donor (D) and acceptor (A) molecules have recently gained attention as a promising material for organic electronics and ferroelectrics. Two major factors which govern their functions are the strength of CT interaction and their supramolecular nanostructuring. Here we present coronene‐naphthalenediimide (NDI)‐based novel D‐A pairs that form alternately stacked CT assemblies. Through systematic substitution of the NDI derivatives and studying their CT interactions with coronene, a clear understanding of the secondary forces responsible for controlling their association is gained. Finally, the use of CT‐based supramolecular amphiphiles for their nanostructural engineering into ordered one‐dimensional (1‐D) assemblies is demonstrated.
