Fluorescence resonance energy transfer (FRET) is one of the most important fluorescence mechanisms, with multi-step FRET systems enabling sequential energy transfer as seen in natural photosynthetic systems. Here, the authors review recent progress in exploiting discrete supramolecular assemblies to achieve multi-step FRET between donors and multiple acceptors.
