Comprehensive Summary: Tuning Förster resonance energy transfer (FRET) in metal‐organic frameworks for fluorescence turn on sensing is rarely reported. Herein, we designed and synthesized several FRET‐based metal‐organic frameworks (MOFs) with different donor/acceptor ratios. Through the oxidation of the acceptor, the FRET process in MOFs can be efficiently modulated so as to turn‐on the fluorescence of the framework in a controlled manner. Interestingly, the MOF with an optimized donor/acceptor ratio of 7.0 was used as an efficient fluorescence turn on sensor for Hg(II) ions with good sensitivity and selectivity. We believe our present study will not only give a useful method to construct fluorescence turn‐on sensors but also trigger the construction of novel FRET‐based MOFs for the fluorescence turn‐on sensing of target analytes in the future.
