Reversible Single-Molecule White Light Based on Controllable Fluorescence Resonance Energy Transfer

Chem. Commun., 2025, Accepted Manuscript DOI: 10.1039/D5CC00927H, Communication Yao Yu, Yongsheng Zhang, Zhenhui Wei , Muqian Li, Junbo Gong Two novel Diels-Alder exo-adduct donor-acceptor dyes were synthesized with different spacer lengths. These dyes display intramolecular fluorescence resonance energy transfer (FRET) from deep-blue-emitting naphthalimide donor to yellow-emitting dansyl acceptor. Temperature-responsive...
