| titleOfInvention | The small-molecular-weight Coumarins near infrared fluorescent dye and its synthetic method of a kind of big Stokes shift |
| abstract | The present invention relates to a kind of small-molecular-weight Coumarins near infrared fluorescent dye of big Stokes shift and its synthetic method.Intermediate is obtained by the reaction such as catalytic hydrogenating reduction, glyoxal condensation, sodium borohydride reduction, the formolation of Weir David Smail, acid catalysis demethylation, then target product Fluorescent Brightening agents based on Coumarin is obtained by the graceful condensation reaction of peck.Compared with existing Coumarins dyestuff, the fluorescence emission wavelengths of coumarin kind compound that the present invention is obtained near infrared region (>700nm), and with big Stokes shift (>220nm), the fields such as luminescent material, biological fluorescent labeling and bioluminescence imaging be can be applied to. |
