A self-calibrating sensor toward fluorescence turn-on detection of DMSO and nicosulfuron

Achiral Sm(III)-Based Metal–Organic Framework as a Luminescence Sensor for Enantiodiscrimination of Quinine and Quinidine

“…As shown in Figure 2a, IMU-MOF1 features four peaks at 564, 604, 649, and 704 nm upon excitation of 358 nm, corresponding to Sm 3+ transitions of 4 G 5/2 → 6 H J (J = 5 / 2 , 2 / 7 , 2 / 9 , 2 / 11 ), respectively. 45,46 The fluorescent intensity of IMU-MOF1 at 604 nm is higher than that of other peaks, which display intense orange-red luminescence, and the position of CIE is shown in Figure 2b. IMU-MOF1 has a fluorescence lifetime of 50.9 μs (Figure S6).…”
