Photostable and bright fluorescent dyes with large Stokes shifts are widely used as markers in far-field optical microscopy, but the variety of useful dyes is limited. The present study introduces new 3-heteroaryl coumarins decorated with a primary phosphate group (OP(O)(OH)2) attached to C-4 in 2,2,4-trimethyl-1,2-dihydroquinoline fragment fused with the coumarin fluorophore. The general synthetic route is based on the Suzuki reaction of 3-bromocoumarines with hetarylboronic acids followed by oxidation of the methyl group at the Ci£C bond with SeO2 (to an aldehyde), reduction with NaBH4 (to an alcohol), and conversion into a primary phosphate. The 4 position in the coumarin system may be unsubstituted or bear a methyl group. Phosphorylated coumarins were found to have high fluorescence quantum yields in the free state and after conjugation with proteins (in aqueous buffers). In super-resolution light microscopy with stimulated emission depletion (STED), the new coumarin dyes provide an optical resolution of 40-60nm with a low background signal. Due to their large Stokes shifts and high photostability, phosphorylated coumarins enable to combine multilabel imaging (using one detector and several excitation sources) with diffraction unlimited optical resolution. A green light for bright ideas! 3-Heteroarylcoumarins with a CH2OP(O)(OH)2 group attached to the 2,2,4-trimethyl-1,2- dihydroquinoline residue absorb at 410-440nm and emit at 500-515nm (see figure). Large fluorescence quantum yields and low cross-talk in two-color imaging (with xanthene dyes) were observed. In stimulated emission depletion (STED) nanoscopy, these phosphorylated dyes with large Stokes shifts allow an optical resolution of 40-60nm.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4175-78-4 is helpful to your research., Synthetic Route of 4175-78-4
