| titleOfInvention | There is the near infrared fluorescent dye of big Stokes shift and synthetic method and application |
| abstract | The invention discloses a kind of near infrared fluorescent dye with big Stokes shift and synthetic method and application, the structural formula of fluorescent dye is as follows: Indoles salt compounded of iodine a and condensing agent b is that 0.5:1 1.5:1 is dissolved in tolyl-acetic acid mixed liquor by the ratio of the amount of material for (1) by the preparation method of this fluorescent dye, 110 DEG C of reaction 2h；After completion of the reaction, concentrate removing solvent, cross post and separate, obtain intermediate c；(2) by intermediate c, and acetophenone, 4 methyl acetophenones or 4 methoxyacetophenones are dissolved in potassium hydroxide aqueous solution methyl alcohol mixed liquor by the amount of material than for 1:3 1:1,60 100 DEG C of reaction 15 30h；30 60 DEG C of reduced pressure concentration 20 50min after completion of the reaction, remove solvent, cross post and separate, must have the near infrared fluorescent dye of big Stokes shift.The fluorescent dye of the present invention has near-infrared maximum emission wavelength, and has great Stokes shift. |
