摘要

合成了两种具有不同间隔长度的Diels-Alder外加合物给受体染料。这些染料显示出分子内荧光共振能量转移（FRET），从深蓝色发光萘酰亚胺供体到黄色发光丹酰受体。温度响应键裂解和间隔段长度调制实现了可控的分子内FRET，实现了可逆的单分子白光发射。

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

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 bond cleavage and spacer length modulation achieve controllable intramolecular FRET, enabling reversible single-molecule white-light emission.
