Tailoring the luminescence of FRET systems built using supramolecular polymeric nanotubes

Abstract

Supramolecular polymeric nanotubes self-assembled from cyclic peptide–polymer conjugates are employed as general scaffolds to fabricate supramolecular FRET systems. The monomer-to-excimer emission ratio of the FRET donor, PYR–CP–PEG, can be simply and reversibly tuned by the introduction of a spacer in the supramolecular structure, thus endowing the luminescent FRET systems with tailorable and responsive properties.
