A novel fluorescent probe for selective imaging of cellular cysteine with large Stokes shift and high quantum yield

Fluorescent probes based on an oxonium-coumarin scaffold for the detection of SO2 derivatives

“…2. 3.68 (t, J = 5.2 Hz, 4H), 3.50 (d, J = 5.9 Hz, 4H), 3.39 (s, 1H), 3.25 (q, J = 4.8 Hz, 4H), 2.89 (d, J = 6.5 Hz, 2H), 2.78 (d, J = 6.4 Hz, 2H), 1.94 (dq, J = 28.9, 6.0 Hz, 4H). 13 2.2.2.…”

“…A wide variety of active sulfur species, including elemental sulfur, hydrogen sulfide, mercaptans, sulfur-containing amino acids, sulfur oxides, etc., are distributed in the environment and found in humans, and have always been the key detection object of fluorescent probes. [1][2][3][4][5] SO 2 is one of the main pollutants, and it is easily soluble in water, which is the direct cause of acid rain. In addition, the inhalation of SO 2 can cause damage to the respiratory tract.…”

Integration of fluorescent probes into metal–organic frameworks for improved performances

“…Structure regulation usually improves one performance of uorescent probes at the same time. [21][22][23][24][25][26][27][28][29][30][31] By contrast, uorescent probes are regulated with MOFs based on host-guest chemistry, which can improve the multiple performances of uorescent probes simultaneously. 57,69,70 Therefore, MOFs display the superiority of high efficiency compared with structural regulation.…”

Molecular origins of the multi-donor strategy in inducing bathochromic shifts and enlarging Stokes shifts of fluorescent proteins

“…S1, ESI †). [28][29][30][31] Notably, in a landmark study, Ai and co-workers have recently introduced a genetically encoded artificial amino acid, 3-aminotyrosine, to the fluorophore of GFP-like proteins and biosensors for ''spontaneous and efficient green-to-red conversion'' (Fig. 1, the right panel).…”
