Multicenter Metal–Organic Framework‐Based Ratiometric Fluorescent Sensors

Metal–organic frameworks (MOFs) with multiple emission centers are newly emerging as ratiometric sensors owing to their high sensitivity and high selectivity toward a wide range of targeted functional species. Energy transfer between the light‐absorbing group and emission centers and between different emission centers is the key to rationally design and synthesize MOF‐based ratiometric sensors. A good match between the energy levels of the...
