Nature is replete with supramolecular structures involving weak interactions. For example, guanine, in the presence of a suitable cation, forms stacked structures known as "G-quadruplexes," while diphenylalanine may aggregate via pi-pi stacking into structures that display quantum dot properties. To this end, an series of adducts of guanosine and diphenylalanine have been synthesized and studied to determine the effect that G-quadruplex formation might have on quantum dot assembly. Circular dichroism and proton NMR studies confirm the ability of these adducts to form G-quadruplexes in non-polar solvents; furthermore, it is demonstrated that quadruplex formation is highly dependent upon the presence of potassium cations, and that quadruplex assembly is reversed if potassium ions are "trapped" by 18-crown-6. Atomic force microscopy and photoluminescence excitation spectroscopy confirm that the adducts synthesized form peptide quantum dots in protic and polar aprotic solvents. At the present, the formation of G-quadruplexes has no apparent effect on peptide quantum dot assembly or activity.
