Guanine-quadruplex (G-quadruplex) assemblies provide a useful platform for studying the spatial, structural, and photophysical effects of intermolecular interactions. Coupling a single guanine moiety to terrylenediimide (TDI)a chromophore with a large extended π-surfaceproduces a structure (GTDI)...
