The method enables modulation of FRET by exploiting the unique reversible spectral properties of photochromic diarylethenes and spiropyrans to create switchable energy acceptors.enFluorescence Resonance Energy Transferjournal_article10.3390/50300591https://resolver.sub.uni-goettingen.de/purl?gs-1/8269openAccess
