Abstract
A diverse set of perylene diimides (PDIs) have been synthesized and studied for their unique self-assembly, folding, and spectroscopic properties. Specifically, substitution in the "bay" positions of the PDIs causes the perylene to twist dihedrally out of plane, modulating the [pi]-[pi] stacking force and directing intermolecular assembly and intramolecular folding, apparent by NMR, absorbance, fluorescence, and single molecule spectroscopy. Dihedral twisting induces chirality, revealing unique properties for hetero- and homo-chiral cyclic and linear dimers. Molecular assemblies formed by differently twisted PDIs reveal an inherent molecular code with preferred stacking between similarly twisted monomers. The most highly twisted PDIs frustrate [pi]-[pi] stacking to the extent they make ideal fluorophores for fluorescent DNA foldamer nanodevices, polymer nanoparticles, and dendrimer biolabels
