WebThe chiral fluorescent recognization of COF Dha Tab-3 for S- and R-imazamox was used as an example in fluorescence measurements experiments. 2.0 mL of the tested sample was taken into the quartz colorimetric cell including 1.0 mL of COF Dha Tab-3 and 1.0 mL of the target analytes solution. WebJul 1, 2024 · These chiral COF-bound capillary . columns were synthesized via an in situ growth approach, which ach ieved the baseline separation of (±)-methyl lactate, (±)-1-phenyl . We prepared Tp-based CCOFs under conditions mimicking those used for the synthesis of the achiral analogs40,41,42,43,44. Thus, the series of (Λ)- and (Δ)-CCOFs were synthesized from a 2:3:2 mixture of Tp, diamine, and (S)- or (R)-1-PEA or 1:1:1 mixture of Tp, triamine, and (S)- or (R)-1-PEA in mesitylene, … See more The Tp series of CCOFs are highly fluorescent, especially TpTab showed a strong emission maximum at 540 nm excited by a λ = 387 nm with a lifetime of 0.79 ns (Supplementary Fig. 35).
